Found some 2v cleavland heads, mild cam, performer intake, decked the blocked,
Balanced, 600 carb, about 9 to 1..
I really don't want to rev it but u know... Just to impress the kids....
Headers, looking for low end torque... Broader C6' np205, bla bla...
Any other suggestions please post up...
Dont waste your time with iron heads, the factory 400 heads are sjit, they crack easily and arent good for performance of any kind. Your best bet is fit a pair of Edelbrock or TFS Clevo heads, keep the Performer but use a 750 vac (remove the check ball from the secondary chamber and fit the lightest spring from Holley), Isky 270 MEGA camshaft, FORGED pistons, Melling HV pump and a good hi-capacity oil pan (make sure the mains clearances are .002 min, as the large 3" main diameter will strip the bearings when too tight due to the high surface speed), the best ignition system you can afford (MSD or ACCEL make excellent systems) and use a quality 15w40 oil (change it regularly). The cam might be a little too harsh at idle, but it will crack like a whip and have massive mid-range torque and power. My $0.02.
