Re: what will a stock 350 TBI in our thirdgens run in a 1/4 mile

too many variables. what gears? what transmission? weight of car? I say with a decent gear 3.23-3.42, 700r4, stock weight car, and a stock 350 tbi running good. 14.4-14.8

Re: what will a stock 350 TBI in our thirdgens run in a 1/4 mile

Ex. You know what we are talking about. You pull out your 305, and put in a 350 tbi, it is identical all accesories mount up. Stock is stock like you pull it out of something with a 350 tbi and put it into your car without doing anything performance to it.

Re: what will a stock 350 TBI in our thirdgens run in a 1/4 mile

I agree that there are just to many variables to this. Give us an idea of what is all going on with this build to help in our "guesstimates" lol.

Re: what will a stock 350 TBI in our thirdgens run in a 1/4 mile

it is not going to be fast!!!!!!!!!!! a 14 would be cool for me. my build is a 350 with 193 heads with slight work, edelbrock tbi manifold, ultimate tbi mods, 180 therm, 4l60e with the 7427 with custom tune, long tubes, and magnaflow catback. 3.23 gears. should be good for a mid to high 14.

Your answer is a far cry from one92rs's answer.

Re: what will a stock 350 TBI in our thirdgens run in a 1/4 mile

he said mid to high 14's I said from 14.4-14.8 which is mid to high 14's...lol...depending on variables and at least a 3.23 gear. with the 2.73s and a good running 350 tbi, good shifting transmission. your going to be around a 15.2-15.4

figure i ran a 14.8 with a **** poor tranny but i had headers,cam, and other small stuff with 3.08 gears at that time. then went to a 14.6 with 3.42 and a horrible transmission. then a good transmission and stall converter down to 14.2

Re: what will a stock 350 TBI in our thirdgens run in a 1/4 mile

another thing to remember also is that a good tranny (auto) will consume about 22hp to run. a standard around the 10 to 12hp mark.
