Can you tell?

I am looking at this 350 block this guy has for sale and he don't know what year or what car it came off of. But i looked at the block and it can be cleaned and bored to .30 but i was wondering is there any site that will tell you what kind of motor it was if you type the block number in? by the way the # on the block is 3970010.

That sounds kinda shady...

i think he is just cleaning out his garage or something. It says gm and that # on the block.

3970010....302.....69....4...Z-28 Camaro
3970010....327.....69....2...Trucks and industrial
3970010....350...69-80...2 or 4

this is what that casting number comes up as. it goes number, ci, year, bolt mains, and what it was from

wow, so it looks like it is the 2ed gen 350. Will that still work in my car? and can i run tbi or tpi on that motor. here is the site where the block is at, i am looking on it at ebay. http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&rd=1,1&item=8057448836&sspagename=STRK%3AMEWA%3AIT

you can still run it with tpi. Just get the right heads to match the type of tpi manifold that you have. (whether the inner bolts are angled or not)

well as of right now all i have is a 305 tbi and i wanted a 350 but i did not know if i wanted tpi or tbi, i am thinking tpi so i will have to get the unit to. I am going to do all forged internals to because i plan on running nos.

I wouldnt do TBI. Yeah a few people stick by it but ya know....How many fast cars do you see with TBI? I think even the 670 tbi will hurt on top end....not enough velocity to make high horsepower. But someone probably has a dynograph to prove me wrong....

ya, and there is more parts for tpi and they are cheeper. I think i will go tpi then, i am going to this this motor little by little so i do it all right and have money. Now i am just going to buy a block because i am saving for my paint. So i can do tpi on this motor?

i had tbi on my 92 rs w/ a 350, it was making close to 350 to the wheels which was plenty for an 18 year old...

don't worry, i'll prove you wrong soon enuff.

ya, but i think i will just go with tpi because i would like to have a daily driver 350 tpi at around 360's hp. To do that with a tbi would take alot more money.

how much power do you plan on geno?

ya but look at his list of mods on the tbi, if you did all of that on a tpi it would have alot more power, i am jusy saying i can get more power for money with tpi. And plus they make a supercharger for the tpi!!

okay, i wasn't telling you to go the tbi route, just telling you i had in the past and tbi was okay for me and geno apparently

altho i do like the sound the tbi makes when you have the air cleaner lid off and you rev it up, but tpi still sound good. I know what you were talking about 6.

nah not really, TPI's are torque monsters, they lose it up top. but that's beside the point, if you wanna put that much power to the ground you're gonna hafta upgrade the TPI itself and that stuff will add up big time. Trust me, I looked into it myself cuz I was gonna make the switch to TPI, but TBI turned out to be the more economical choice. TBI done right can put over 500hp to the ground.

a tpi with the same mods as mine won't put out much more power at all, if even any at all. and there's a few supercharger choices available for TBI.

yea I'm not trying to tell you what to do either, just stating the ofter unknown and overlooked facts.

i was think of one of thoes aftermarket tpi system things. they have the tubes that run to it and the intake is all flat on top and is like a squar. It is soposed to help alot with it flating out at higher rpm's. But with the block i showed you guys, can i even run tbi on it?

ther's a supercharger for the tbi? where i have been looking all over for one and can not find one.

i've seen them too, i cant remember because i'm sleepy now, but that was the plan when i got the 305, then school, looking for a better job, and other little things ended that idea.

any roots style blower for a carbed V8 can be used with TBI. They make adapters to put TBI's on carb manifolds.

you mean the stealth ram? that's over 2 grand ya know.

ya i know it is expesive i do not know who make it, i will look in to it. But i think i will just go ahead and buy that block off ebay you think? it is only $30.

ya i know it is expesive i do not know who make it, .

Holley and a few others

accel makes a tpi setup as well.

well if you are going to spend the money that you say why not just use your block and have it bored over because a 305 and a 350 are about the same it is a small block chevy just have differant bores.

i know but if i have a 350 i can get more power for money, and i am tired of the 350. And this is my daily driver, so i will not have anything to drive while i am rebuilding the 305.

How do you figure that??? You get a junk yard 454 throttle body, bigger injectors and a tune and your set, maybe cost 300 to 400 bucks, less if you tune it yourself. Plus you can use any carb style intake manifold and an adapter plate, can't do that with TPI. I really don't thnk that you can easily or cheaply get 360 hp out of a stock TPI intake, if at all.

EDIT: I just looked throught the thread and geno pretty much said the same thing, guess I was a little late with this one

ok,ok i think i am going tbi now, but will a 454 tbi fit on a 305? i thought only on a 350? i will run tbi, but i think i am still going to build my own 350.

yes it will fit on the 305

ok, so here is the update, i did not get that block because it was going to be $250-$350 for shipping. So i am just going to keep my eye open for a 350 block that needs rebuilt. And i will run the tbi system on it with the 454 tb.

the stealthram system with the computer management system and fuel kit with injectors and all is over 2000. The manifold itself can be had for around 500-600 dollars. Buddy of mine is running that system and is making about 360hp to the wheels with a mild 355 build. Doesnt seem like much till you look at his torque which is about 430ft/lbs. I think the tbi will be more work but like he said geno is going to prove me wrong.

thats essentially all you would be building. I know it will make good power, just seems like a hard way to go. With a tpi system with the stealth ram manifold and the right cam and tune and ported heads you can make very good power and youll have your top end. Not a lot of it but enough. Like my buddy's car with 430lb/ft. That torque is what is going to get you moving.

i am still kinda still unshure but i am leaning towards tbi because it is cheeper, i was looking at the FI kits for tbi motors but they are like $2,000. So i think i am still going to go tbi.
