my dad informed me that once we get his blown 85gt running perfect so i can dd it, its time to do the motor in my car. i will start off by saying the car will be a daily driver, and smog is not an issue. i have a 88 gt and my motor is slowly loosing power, burning oil, and there alot of codes popping up. right now i supposedly have a 30k mile shortblock, stock heads, gt40 upper/lower, 24lb's w/ granatelli, and full exhaust(motor built my previous owner, i have random reciepts and still trying to figure out why car is so fast- dynoed 290rwhp 327tq by previous owner). anyways, its time to build a new motor and i need some opinions. my goal is 400rwhp and still be streetable. 1. i could rebuild my motor with a 331 stroker kit, either gt40s or 351 heads, new valvetrain, etc and keep the efi, but i HATE working on efi, and with how messed up my car is right now id rather not go this route. 2. i could build a mexican 302 with 331 stroker, 351w heads, and go carbed. 3. a mild 351w build, carbed, with worked heads, nasty cam, etc. or 4. tear down my motor, figur out why its so fast, do rings, get some trickflow or afr heads, valvetrain etc... but i dont think ill get the power i want.
