i am going to sell my car and i am looking at a 1986 trans am. it has a 305 auto, t tops and stuff. it has like 150,000 miles but so does mine. should i do this or not. how much faster will it be than my 2.8? and anyone know what they turn in the 1/4?

 

if it's TBI stock for stock little to not all faster

but the 305 is easier to modify

IF IT'S IN REALLY NICE SHAPE, stock etc, really really nice, grab it.
Those are starting to become collector cars. Get it real low & keep it stock.
It will increase in value in 2002, big time.

it'll depend alot on what type of 305 it is. remember not all of the T/A's are Tuned Port, many of them are Throttle Body. I raced a 91 TBI camaro a few weeks back and we ran dead even, so they're not entirely fast, on the other hand a good 305 TPI mated with some 3.23 gears, will be a nice ride to take out some of them hondas. IT all depends on you, i wouldn't mind picking up a Tuned Port 305 myself, but a TBI i'd leave right where it is.

 

it is a 305 TPI. all he has done is put in a shift kit. he said even with the high miles it runs really strong still. he said it should run like a high 15 or so?

305 means easy jump to a 350 or a 327 or a 334 (Stroked 305 with a RHS KIT).... If I could get a car as nice as mine, but it was a trans am over a coupe camaro I would consider it. Less miles and nicer than mine I would do it iin a second.
