Modifying my Camaro RS

Ok guys ... I recently purchased a 1991 Camaro RS with a V8 350 in it. The body is in great condition but I want to modify the engine a little. I am pretty new to modifying cars and everything but I would like to get into it and I was wondering if anyone would help me as to what I might start with when adding modifications to my car. Any suggestions?

World products torquer 305 heads, holley 670 TBI unit, Edelbrock performer intake, TBI to 4bbl adapter, edelbrock performer rpm cam, edelbrock TES headers, high flow cat, flowmaster cat back exhaust, mallory 50k volt coil, msd 8.8mm wire custom chip( programed with better fuel mix and advance curve, and low temp thermo) and a 160 stat. I think that's a good starting point.

uummm... he said 350...

Is it TPI or TBI or Carbed?

if it is a 350 I would find a better head then a torquer 305 for it.
Also if it is a 350 dont choke it off with a puny 670 cfm 2bbl tbi unit. Fricking go carb and forget about the computer! It is possible to pass emissions with a carb!!!

torquer 305s are absolute junk for a 350. they are designed to be a high performance 305 head because 305s have tiny bores that can't accomodate large valves like a 350 can. a holley TBI unit would be a waste of money, get a 700 cfm holley double pumper, 1 3/4" SLP headers if you are going to stick with shorties, otherwise, get long tubes, since you've got a carb don't bother with a chip, all your tuning will be mechanical and thus EASIER TO DO. get yourself a set of Dart Pro 1 heads (they are about $1000 if you know where to look), they are aluminum and you can get them as large as 230cc intake runner which flow over 300 cfm as cast! get a nice cam like a 284HR comp cams or a ZZ-409 or ZZ-X TPIS cam. you could make an easy 500 HP with that and have plenty of nice streetability, even get 20+ MPG with an overdrive transmission. then again, if you want to run low 14s and be content, you can do the build 1992RS suggested.

if it's a 350 it should be a tuned port, i think tbi was only on the 305 and some V6's

Also if it is a 350 dont choke it off with a puny 670 cfm 2bbl tbi unit. Fricking go carb and forget about the computer! It is possible to pass emissions with a carb!!!

huh? 670 is about right for a 350, i would wouldn't go any bigger than 750 carb, and even with that you probly wont get it's full potential out of it. carbs suck

huh? 670 is about right for a 350, i would wouldn't go any bigger than 750 carb, and even with that you probly wont get it's full potential out of it. carbs suck
yeah they suck so much which is why they are always faster than TBIs

my tbi would stomp your carb. i've had carbs and they are worthless. i had a quadrajunk on my 350, and yes it made pretty descent power...ONCE IT WAS WARMED UP..and after the 4 hours i spent tuning the damn thing adjusting junk thermal choke.

theres your problem QUADRAJUNK!
Run a real carb!
And V8punk is EFI not Carb

I have a nice carb setup going in my camaro feel free to bring that TBI garbage down here and run me. If you want I will even run you with my old TBI unit sitting in the seat next to me. Because that is all its worth and all it is. DEAD WEIGHT!

Damn, these guys where finaly right about something, I misread the 350 for a 305.

BRING IT! IF YOU DO YOU WILL BE SHOT DOWN!

Dude, you've already been shot down. I have the respect of these guys, the guys in my F-body club, the guys that I stomp on the streets and at the track. Why should I need prove my self to you? No one respects you, and after today I'm sure no one will even remember you posted here.

Pull your damn head out of your ass.... Aint my problem if everyone here is a fucking lemming and I wont follow you. Does 100 dumbass people following an idiot make the idiot any smarter? No. So pull your head out of your ass and check the links I provided. I havent been shot down. Its just been proven to me that if 100 people follow an idiot then that idiot thinks he is an all power all knowing douche bag.

13 second cars don't stomp anything on the street or track other than imports.
four on the floor, quadrajunk is a predecessor to TBI, they all suck. the only decent induction system GM has ever had was the LT1 intake. as I said before I'm EFI, not carb'd, if I didn't have a daily driver, I would be running a carb. I like getting 30 MPG and running "FAST". your TBI POS must be a big block if you think you can stand a chance.

Well at least these guys are intertaining.

So check the links and people decide for yourselves before following the lemming infront of you off the next cliff.

ok :screwy: i guess we've forgotton the concept of big block torque and hp too. go tune ur carb. you've pretty much bashed tbi,tpi and even managed knock down a carb in one of your posts, which is what your trying bost about. when you come up with an alternate source for gasoline induction ya let know
what are you and twin89 boyfriends or something, you seem to have ur heads up each others asses.

there's always a different side to each story of what's best and ya cant base your idealistic beliefs on something you've read on 3 web pages. i've been to those pages in the past, and i've also been to pages that contradict everything they say. i post in reference to my own experiences and not to what a few gearheads on the internet say

TPI is nice for a 305 but it starts restricting upper rpm power.
TBI is nice for a low rpm truck but is not a performance application.
Quadrajunk self explanatory.
Standard carb. Not the best solution but actually better than TBI. Though not as good as a TPI system upgraded with a stealth ram.

Not bashing each one. simply showing pro's and con's if you take offense then that is your call.

as for the gay comment wow I am not the ass bleeding douche bag that uses frozen tampons to stop his ass bleeding caused by 1992 RS... and you should of asked him he prolly would of told you he had anal warts and crabs.... if you had asked then you would be stuck in this situation and you might realize that I am giving you the info you need to check out both sides of the story.

uhmm that was a little hypocritical. why dont you just go ahead and create your other user name and pretend to be someone else, cause your not gonna be around much longer

Check the ip's
we arent even in the same city dipshit.
2 different people.

And of course we wont be around long. We arent lemmings we wont follow all of you off the side of a cliff. Trying to show you guys that a lot of this info is incorrect. If you choose to jump off the damn cliff not a thing we can do about that except for make bets on where you will land and how big of a splat you will make.... though I got a feeling a lot of you will bounce...

Ya know, I do actualy like people like you. People like you are the reason I did build my 305 instead of throwing it away. I like to do things because people say it can't be done, or it shouldn't be done. I'm a big fan of the underdog. I don't care what your car club says, I really don't. I know what I know, and that comes from experiances of my own. Not what someone else told me was right. I know what works and what doesn't. I build engines profesionaly. I actualy make money making people go fast. I've seen it all. I've seen carbs, TBI's TPI's MPFI's, Ram jets, Stealth ram, tunnel ram, MFI, I've seen and done it all. Hell I've even built my share of LT1s and LS1s. Don't tell me I don't know what I'm talking about. So take your foot out of your mouth and do something usefull with it, like walking away from this forum.

Proof?
and why dont you pull your foot out of your ass because your obviously full of shit and its starting to back up... its explains why what comes out of your mouth stinks so bad...
And I thought about making my 305 perform but fuck that my 2.3T Mustang has more potential!

what's w/ the cliff thing? did u have a bad childhood experience?

Ok, this is enough. As far as I'm concerned and I'm sure everyone will follow me, this thread is closed. There are people that need advice and we are doing them no good going back and forth here. Don't post anymore because your waisting every ones time. Good day gentlemen.

Read it fine. But thats troll behavior so I went ahead and made it clear!

As far as you weenie I mean queenie I am sure everyone will follow your bleeding ass off the side of the cliff.


Why do I keep referring to a cliff well lemmings will follow each other off the cliff and thats what you people seem to be!

just seems like an obsession to lemmings and cliffs to me... are u one of those guys who runs around paranoid that the sky is falling? i'm genuinely curious...

Just leave em alone storm, there getting a kick out of this. There like a little brother, they just do it because they know we'll react to them. So lets not give them satisfation in that.

got it

Nope actually I live life day by day and take what life hands me.

Just this part of this site reminds me a lot of lemmings walking off cliffs following one another... everyone doing the same thing only to discover they all reach a performance cap at a point because of following said idiot in the mean time all the other people are flying past.

As far as 1992 RS is concerned lets run em!
lets find a road course and run em! A real race not just drag racing!
you know lets do gas brake turn gas brake turn gas brake turn... not gas gas gas gas.......... brake...
lets see how well your dinky 305 does then!

Thank you everyone for your information ... I have had my Camaro RS for a couple of months now and I already love it ... I am really going to enjoy working on it, but not as much as driving it afterwards (dont worry I wont try to pull a U-Turn in the rain and wip my ass end out only to go spinning out of control towards another vehicle) ... and im not trying to follow anyone anywhere on this one but I did post this forum for help on modifying my Camaro and I figured that going to a automotive forum that is based for Camaros would be a great starting point to get some ideas of what I should be doing, this doesnt mean that I wont post any other questions or want anymore advice, but I do believe that this forum is done serving what it was ment for... for those who want to still give me advice it is always welcome at [email protected] and I would appreciate any other advice that you guys have to offer because I do know one thing ... you all probably know more than I do about the modifications that can be done to a 91 Camaro ... once again, thank you.

don't listen to these slow ass magazine and internet racers telling you to keep TBI. its pathetic, no one runs TBI if they want to go fast. 10s from a 335 is the biggest load of bullshit I've ever heard, almost as bad as hearing about 10 second imports. these self-acclaimed gurus are just jokes.

[QUOTE=AJHD91CamaroRS] The body is in great condition but I want to modify the engine a little. QUOTE]

Look.. The guy said he wanted to modify his car A LITTLE.. hes new to mods and obviously isnt shootin for no 10 second super car.. He wants a few suggestions.. Why dont you all go back to his question, think about it for a few minutes, than offer some HELPFUL info???

Ide say, forget everything everyones been arguin about, and start with the basics! Get a good decent exhaust, Edelbrock TES headers would be my choice, high flow cats, a good performance muffler.. Borla, magnaflow, Flowmaster.. etc.. As 1992RS has already mentioned...

Also, to help the engine breath a little better, you should have the dual air intake correct? Well, pull your filters out, remove the 4 small vent blockers, and cut some big holes in the plastic to let more air in.. Put k&n filters in.. 1992RS had also mentioned an aftermarket coil, and MSD 8.8m wires, I wouldnt use anything less.. But I like to keep my componants matched so I would suggest an MSD coil instead,

Ide definatly stick with fuel injection, especially if the car is a daily driver.. A carb will never compare to the fuel economy and reliability of a fuel injected vehicle, thats why they dont make them anymore.. and you'l be limited to mechanical tuning.. Get a Hypertech thermomaster chip, with a 160 degree thermostat to help the engine run cooler..

Any more than that and you should start looking into internals, high-flow heads, etc.. You'l also want to built up your tranny to handle the added power..

Hope this has been of some help

homos

Dont bother with hyperjunk Hit up pcmforless they do a much better job. As for not making carbs anymore wtf? Tons of companies still do and the fastest cars are still carbed! How wierd...
As for as a carb not being reliable... Who says? My TBI has been more of a headache than the carb on my 88 mits which by the way has never been touched or tuned since the factory! and that has 160,xxx on it. Wierd....

For the most part I agree with the mods. Though I am not a fan of edelbrock headers. I prefer heddmen or Hookers. I also dont care much for flobastard just too many people have them and too many camaro's sound a like. I hava hooker aerochamber 3 inch cat back on my car. I love the way it sounds and if hooker made a 4 inch one I would buy it but they dont so I am off to spintech to get my next cat back. As far as cutting holes and stuff for the air filter just run an open element I have been for year + now with not a single problem. I even cleared inspection and emissions with it. I do agree with the hi flo cat however I have heard of people having problems with them passing emissions so make sure to pass before doing the mod. The LO3's biggest weaknesses are pretty much the whole top end of the motor. Heads cam and intake. The cam is weak as hell. Even a stock LT1 cam is a decent upgrade to it. Or L98 cam. As far as heads if you want to remain factory and increase cfm ratings. Then I would suggest a set of 113 factory castings. I am however not sure of the valve size but you will need to keep it at or below 1.94/1.50 thats the max valve size for a 305. Also the 113 are aluminum heads and 58cc so your compression will remain correct. Other cheap factory heads would be LB9 Cylinder head which would help out or 461s with tha 1.94/1.50's Though do measure the valves if you go for 461's since many are fitted with 2.02/1.64 valves. All of these heads with exception to the 113 you can prolly find cheap. My 461's came ported polished with big valves and are the 57cc heads. I only paid 150 for them. Great deal. So look around for parts. If you have a high mileage 305 a set of heads might not be a bad idea as typical 305 LO3 heads develop valve seal leaks due to the o ring style valve seals. So by doing new heads you fix this problem or future problem increase power replace head gaskets (bit of extra security there) and make the car more enjoyable to drive. As far as MSD. I do like their stuff but I went with a crane Hi-6 box on my rs and even with just the cat back and open element the car felt much more responsive. I prolly overlooked some stuff if I did I will come back to it.

I totally agree... The fastest vehicles in the world are carburated.. But as I mentioned, he wants to modify his car a bit.. Not build an alchohol funny car..

What I meant was that they dont make carburated vehicles anymore.. Although its a matter of opinion Ive owned carbd, and injected vehicles.. and Ide never go back to another carbd engine again...

first and foremost, 92RS knows his shit, case closed, argue all you want, you make yourself look like a douche. also, an LT1 cam wont go into an old school smallblock to my knowledge, could be wrong there. but eh.

to the question, if the guy is even still checking here, if you got the 305 and you just want to wake it up a bit, i would say a set of world products SR torquer heads for the 305, a comp cams xtream energy cam for computer controled cars, edelbrock performer intake, and holly throttle body, or for a cheap upgrade, the trottle body off a truck with a 350. headers, high flow cat, and xhaust. but also, dont just focus on the engine, the biggest change in my cars speed was dropppin in a 2600-2800 stall converter with a kevlar lockup clutch, and a full B&M 700-R4 with a stage two shift kit and corvette first to second servo, next up is a torsen rear end with 3.23 gears. but also concider your suspension, the stock units are weak and bend and flex on takeoff, loosing you reaction time, upgrading to tubular stock, with polyurethaine bushings and stiffer springs have cut as much as half a second off acceleration times at the track, and subframe connectors are the best investment a camaro owner can make in my personal opinion.

oh and not to be a dick, but the fastest vehicles in the world are jet powered, so they dont have carbs ;)

oh and im not a lemming, i actually agued with 92RS bitterly about TPI vs TBI the first post we had together, but sense ive been here long enough to have more than one argument, ive actually learned that he knows his shit, rather than deciding that because one guy disagrees with me, and people back him up, that everyone here must be idiots and followers, how patheticly infintile.

Umm yeah, what he said..

I agree for the most part 89Iroc...

Stall and built trannies seem to help the auto's out a fair amount on these cars. I havent personally used an LT1 camshaft but seem numerous threads about it on thirdgen.org and people say they are running them.

As far as suspension I HIGHLY agree with this. I have 36mm WS6 from bar and 21mm WS6 rear sway bar with polyurethane bushings and links. This with the edelbrock springs edelbrock strut tower brace made it completely different feeling and I love it!!!

Just so you know I am still looking at these posts and I am thankful for everyone's imput, I appreciate it. I can't wait to start modifying my rs over the summer and all of this information is going to help me for sure ... I'm going to love working on it ... Thanks. :)

Oh yeah and I actually have the 350 in my rs

well in that case, may i scream at the top of my lungs VORTEC HEADS!!!!!! they are iron castings, so you can get em cheap and they flow like crazy, better than stage two bowtie castings. grab em from the junkyard off a wrecked tahoe or suburban and use the money you would have spent on better heads, to have the vortecs worked over. everyone things you have to machine the valve spring seats and valve guides for performance springs but comp cams sells beehive springs that will fit over the stock valve seats and guides, and allow up to .525 lift. :)

Or you can get your valves .100 over sized and get double springs that'll allow a 600 lift cam.

I would of gone vortec if I had the cash but ported polished big valve 461's with a bracket master II lunati cam is fine for me heh... though not exactly street legal lol.

Vortecs are defintely good heads! And if you have the 350 then get the larger valves. 2.02 -2.08 intake 1.64 exhaust vavles will do fine.

92RS, good advice, the only problem with vortecs and double coil springs is that you have to machine down the spring seat for the larger diameter outer spring, then machine the OD of the valve guide to clear the inner spring, and also machine down the top of the valve guide to allow for higher lift without binding or impacting the spring retainer on the top of the valve guide. which would also crush the seal, and cause oil consumption. for a mild street engine, the comp cams beehive springs are cheaper, and .525 on a street car should be plenty, if your gonna use the vortecs for all out performance, then do the machine work, and you might as well have them angle milled down to 50cc's while your at it ;)

umm the springs I got didn't require any machine work to the heads, they where double, but small diameter, came with seals that where ready to roll.

on vortec heads???????

oh yeah, vortec...damn it. Ya know, the 881 heads flow pretty close to the vortecs and there cheaper, and don't have to mess with the spring seats.

881 castings close to vortec??????????? again i have to question that... flow numbers?????

Do you want numbers or do you want to race?? LOL

hahahaha, not sayin your slow man, just arguin that the vortecs have much better port design, also far better designed chambers.......wait a minute, am i thinking of 882 castings????? what did the 881 castings come on?
