HP guess

I wanted to get a couple of different opinions (guesses) as to how much hp to expect out of my engine, vortec 350 with 114K and 265hp now, with the addition of a comp cams k-kit, edelbrock performer intake, Hypertech PPIII, comp cams rocker arms and push rods. given just that a mechanic i know said i should get upwards of 350hp easy. also at a later point i may get an air intake kit, headers and complete new exhaust, and a bigger throttle body. Any estimate you can give would be great cuz i dont wanna pay big $$ for stuff and only end up with 300hp.

well if your just gettin the cam really it might open up your intake and exaust ext. and dur. a bit but w/ out the larger headers and exaust and a decent intake it dosent really perform to its potental now granted u will get a great change but untill u open up all the aspects of air in and air out u wont be able to really shine w/ all its potential...think bout it like this ok u r an athelete and u do all kinds of conditioning to breath better during a match of some sort, then before the match they give u a straw and tell u u have to breath through that the whole time. yeah ur gonna do better than u would b4 your conditioning but no where near as good as if they actually let u just breath w/ out that big restriction if that makes any since. i know its a corny way of looking at it and there is more too it than that but its true..a cam will let u take more air in and out but if u have restrictions at the entrance (intake) and exit (exaust) its still gonna be hard to do

i have a plenty free exhaust, true dual flows and i now have cut-outs so there is nothing restrictive about my exhaust. Also i plan to buy shorty headers as well as high flo cats and new 2.5" pipe at some later point. as for the intake its stock, basically, i will occasionally take the top of the box or take the filter out and put a less restrictive mesh filter in its place. But i know what you mean anyway, all i want is a number for hp. cuz if i get all this stuff costing around $2000 and only end up with a lil over 300hp im not gonna he a happy camper.

oh shit dude i didnt even read your post right for some odd reason i thought all u were getting was the cam kit and power programmer i didnt even see the intake on there im not an expert but i would say especially after the headers u should be upwards of 350 pretty easy but it could be more if u work on getting it programed real well w/ red light and mapping out fuel, and timing and stuff like that i still coulda swore though that the vortec intakes were expensive so id still call summit and make sure thats the one for your vehicle...o yeah and one more thing i thought the k kit came w/ push rods i know they come w/ the lifters but i thought it included the rods too

oh and the vortec heads already have pretty good flow compared to other stock heads so 89iroc says and i belive him cause everything hes told me he knows what hes talkin about so i could just imagine what they would flow if they had a good port job on them

oh and the future bigger throttle body and injectors should feed that combo real nice and open up even more power

yeh i know what ur sayin. i found a fuel pressure regulator and a bigger throttle body. but im havin problems finding the right injectors, guess they dont have to be made for a truck engine just as long as they fit and work right.

but over 350HP is worth it for the cost of the cam kit, which btw is a cam, lifters, springs, retainers, valve locks, stem seals, and timing chain set; intake manifold and programmer. but while puttin in the cam kit and intake would it be a good idea to wait until i also have the rockers, rods, and valves? and are valves even worth it? when i picked out valves there were two different sizes, whats the difference?, i picked the smaller ones. prolly wont get the exhaust and air intake right away, that will come later but i think i'll get by fine w/o for awhile.

Interestingly enuf, i work for a plumbing company and one of our upcoming jobs schedualed for early spring is for a diesel mechanic plumbing some lines on a new dyno-meter, so if i work the angle i mite could get a few test runs. :evillol:

Why do you want all that horse power in a old truck ? Just get one of the new ones with like 410 HP and then trick that out. If you get a diesel , You can get one of those Six-gun paks from bulley dog and that can really unload some power to the wheels , seen that one on trucks and I was friggin surprised at the amount of Hp it adds and unlocks. while remaining street and emission legal , with a 6 stage kit. 1 stock - 2 stage 2 , yadda yadda so forth. It would be more reliable for the power than a gasoline truck would be as well. By the time your dumping all that money into your 97' , you cuold have traded it in and gotten a newer truck with the money you would have spent on mods for the 97 and come out on top with a new truck and more HP than if you had invested into your 97. Just a thought.

which K-kit do you have????? lol, i know you got the cam, lifters, lube, and all that, but i dont know which cam you have :)

All it says is a high energy cam and the rpm range is 1500-5500. costs of what i wanna do to my truck, under $3000. cost of new truck, over $30000. not gettin a new truck for a long long time.

thats what i was sayin u really need to call comp cams and have them give u all the numbers and the part number for the kit if u dont know alot about them i wouldnt just be guessin which cam to get just by the rpm range of it first call summit 18002303030 then they can give you the number to comp cams thats what i did, and as for the valves u may not need new ones this is gonna be hard to explain but i read that the valve kinda receeds down at an anle then at the end of that angle i kinda just cuts straight down if that makes any since and if u still have that little area left that just cuts straight down and its not to worn they should be okay never worked on them myself this is just comming out of a chevy magizine so i leave that up to u

well goin by the rpm range listed i could only get 3 of them cuz i never see above 6000rpm. but yeh i was told by a friend that gettin new valves really wouldnt add any power at all. i dunno if you know Slowprocess or not but he has a newer silvy that runs 12's on all motor and he said gettin the heads ported and polished may add 30-40hp and i described what all i wanted to do and he said it should get me around 350-400hp total. still wondering if the rocker arms and push rods are worth $235.

what are u planning on gettin a set of roller rockers or what and just call comp cams and give them all your info man they will tell u everything u need to know about which cam to choose im tryin to tell u its not something u just wanna look in the book for and they have alot more than whats listed in summit cause the one they recomended me wasnt in the book

Yeh im gonna contact someone from comp cams about a more specific kit info and also what kind of inktake would go well with it. and a set of roller rockers is what im thinkin about as far as that goes but i dunno how much it would be worth it. the way i look at it is if the rocker arms and push rods dont get me around 25-30hp its not worth it.

roller rockers are worth 10-30hp depending on the application, pushrods are not nessesary unless you have reason to think they will fail on ya.

Ok sounds like a decent buy but i dont think ill get them right away. not interested in spendin a ton of money on this so eliminating things like valves and push rods are welcome.

BAD NEWS BEARS!!! Contacted the people at summit and they said the Comp Cams K-kit wouldnt work well with my truck. so the guy sent me some info about a bunch of parts from Crane. now the k-kit was $310, and to buy the stuff from crane that came in that kit would be $634. That just doesnt sound quite right to me. So i told the guy to try something different and i want all the parts that are in a k-kit and a cam that is designed to be used with a computer for less than $400. so i'll hafta wait and see what he comes up with.

I wanted to get a couple of different opinions (guesses) as to how much hp to expect out of my engine, vortec 350 with 114K and 265hp now, with the addition of a comp cams k-kit, edelbrock performer intake, Hypertech PPIII, comp cams rocker arms and push rods. given just that a mechanic i know said i should get upwards of 350hp easy. also at a later point i may get an air intake kit, headers and complete new exhaust, and a bigger throttle body. Any estimate you can give would be great cuz i dont wanna pay big $$ for stuff and only end up with 300hp.Well 2 tell u the truth with out the cam spec ,intake flow rates,head flow rates and valve size,rocker ratio,and a few other things it is hard 2 tell the amount of hp u will make.But just 2 guess for the hell of it i would say 325-350 maybe. But with that much mileage and upgrades only to the top end of your motor you will put alot of stress on that old bottom end and may kill your ride. So if you want to do all that you might want to put new rod and main bearings in it also just to be safe,but thats just me.
