Customer q:

I have a '78 Pontiac 400 stock and I want to rebuild it to make 450hp 9.5:1 pump gas. What parts or kit would you guys recommend?


ac = No

drivewheel = 2WD

engine = 6.6 V8 400

fuel = Carb

make = Pontiac

model = Trans Am

pwrbrk = Yes

pwrstr = Yes

trans = auto

year = 1978


Using a fresh 400 short block, you could use Edelbrock top end kit #350-2053. Using this kit, you will make around the 470hp area.
