tpi questions

[lozanoa11]

well im in a search for a car. I love lt1 4th gens but latly ive been leaning tword third gens. The problem is i never liked the tpi engines. What kind of numbers do 350 tpi's put down in tearms of power and 1/4 mile times stock? I could swap a carb set up if i wanted to correct? Its just lower fuel pressure and different ignition system right? thanks

yeah you can swap them. You could swap a TBI on as well. I think you'd b better of sticking with the TPI though.

ok i just drove a 305 tpi once and i wanted to cry b/c of the slowness. i didn't know how the 350's were. i was actualy thinking about getting one and later swaping a big inch lsx.

Theres a guy on thirdgen.org who has a tpi drag Camaro. It runs 9.3 in the quarter. Then agian this is not a street legal car though.

Never driven a 305 TPI...

I've been in a 350 TPI and it was beautiful. I know it had headers and exhaust and a K/N other than that i think stock.

All else fails if you find one for sale.. Test drive it...

well id like to make a street able low 11 to mid 10 sec car. do you think this is possible with a tpi with out a rediculous amount of money and/or boost? Thats why i was thinking big inch lsx with a cam and heads should easly get me into the 11's. if not 10's. and nothing a little spray cant fix

Ran a 14.66 with my 305 TPI back in the day. Minor bolt ons w/street tires. Doesnt matter what you start with 11 second cars are created with A LOT of money.

Takes alot of money to make a TPI style induction car fast....but it can be done. Many out there have done it.

[lozanoa11]

how much crap did you go through to get the ls1 in? i know electronics kmember, but what else is involved?

[Naterman35]

Alot of people if they do an LS1 swap its also done with rear, dash, tank, driveshaft... and a few other things.

[Naterman35]

for just an LS1 and tranny your going to be spending a few thousand... Thats for a plain stock motor/tranny.. Not including heads/cam/exhaust/fuel delivery/spray and anything else you want.. Not to mention the price of the car its self... along with getting the motor sitting inside and running.


I would say buy a car with a 350 TPI... You can put heads, cam, full exhaust, SFC's, and some machine work done for probably cheaper.... then if you had money left over could throw a alluminum driveshaft, possible posi, and tires....

If you want to be different get a 305 bored to 334 and get an LT1 head/intake combo =] Im not sure of anyone with that..


But if you have a ton of money and tiem to spend go straight to the LSX

[jakes_GSXR]

i got a 350 tpi and i kept up with a ls1 SLP package friday night. he was gunna get away after 40 45mph tho.

[lozanoa11]

why rear? if i go lsx its gunna be all out so i expect to spend alot. i may start with a new block.

[Naterman35]

why rear for the the 350? Well you'll have money left over compared to the lsx and could afford to get a very nice rear with posi and discs.

[lozanoa11]

ohh i though mabey you had to. yea i figured s60 or 12 bolt
