Help building stock 305 TPI
So i have a stock 1990 GTa with a 305 TPI with the 700R4 trans and im looking into building a street legal speedy car....
Ive installed a K&N air filter and have plans for headers and straight pipes back to flowmaster dual exhaust
i have people telling me to buy this and that and throttle body spacers and blah blah blah, so i figured id come here to ask for advice and recommended parts.
Thanks guys.

Re: Help building stock 305 TPI
Headers, 3in exhaust, 3.42 posi, s10 torque converter, shift kit. This will make it feel like a different car. Next steps will be costlier but will put you in the playing field with the 350s, aftermarket heads, LT4Hotcam Kit, 1.6rr, bigger injectors, custom tune, better runners+ intake+ throttle body..etc etc.. Or...get a 350, save some coin. Its just up to you and how much cash you wana spend.
