i have a mostly stock 89 ta 305
at the time of these races i only had a flowmaster muff. msd ignition and a airfoil

from about a 20 mph roll i stayed even with an lt1 camaro
(think it was bad driving, he droped back a little everytime he shifted then cought back up)

im pretty sure i would have one this next one but still mid 90s firebird jumped way out in front of him.. then got destroyed by a ss... hahha

then i absolutly smashed a mid 90 eclipse (non turbo)

and finaly my friends 02 rsx base 5spd

do these sound right?

 

Hmmm, sounds like you might be running a 350, check the back of the block and see if it said 5.0 or 5.7, you might get a surprise.

 

Yeah Ummm, are You sure You have a 305? Even better yet... Are You sure that You weren't racing V6 4th gen's? An LT1 car should absolutely crush a 305 TPI car! I know there's many variables involved but something doesn't add up here.

 

yeh i dident think this seemed right which is why i made this thread... but im positive the it was an lt1 i know the kid.. hes wasnt that great of a driver.. but still it shouldent of been close... im still tryin to make sure my engine is the original... i put the vin in carfax it came up as a 305 tbi, but its obviouly a tpi and the rpo code says 305 tpi

 

what is the 8th letter of your vin? At least that will tell you what originally came in the car. E is 305 TBI, F is 305 TPI, 8 is 350 TPI. Somebody may have thrown a 350 in there!

 

yea cause you take a 350 block throw on the 305 l98 tpi intake and heads and you got a "305 TPI" the blocks are the almost the same in look and alot of there parts are interchangeable

 

Yes the blocks look the same and the parts are all completely interchangeable.... But there is no such thing as a 305 l98 intake with heads thats gonna make it a 305 tpi. If You have an L98 block and throw a TPI setup from a 305 it will still be an L98. The F body TPI intakes are the same whether it came from a 350 or 305.

 

yeh its possible ive already ran into a few small surpises on this car that the owner didnt mention.. such as the exaust from the cat back was already 3", and there was a hypertech chip in it.. but other than that the engine bay looked pretty stock.. but the guy used it mainly as a show car so he possibly was tryin to keep a stock look

 

yeh the vin claims its a 305

ive been tryin to think of some other losses ive had to see if that helps, all i can think of at the moment is
camaro ss
96 bolt on mustang cobra
(got killed in both those)
and had a close race with a 02 or 03 crossfire (base 6spd)
lol that one was actually my moms car but belive it or not shes a pretty good driver, i think i could have got her from a dig cause i dont think she can launch though, and i had a cat that was starting to collapse but it wasnt that bad a the time so i dont think it made that big of a difference

 

Check the block casting plate, if it's a newer style block, it will say "5.7" or "5.0" on it. The plate is on the driver's side against the firewall.

 

alright ill check that tomorrow and see what i find
