How About Building Me A 318

Okay, let's keep it as 318 as possible, meaning 318 heads. So use KB167 pistons and "302" casting heads. Keep the heads pretty simple, 1.88/1.60 valves, bowl blend, narrow the guide bosses and port match to the intake you already have. Maybe a 30 degree back cut on the intake valves if you use OEM style replacements. And, if you want to keep it really retro, a solid lifter cam like a Schneider T132-F, or even a Comp 270S. Short tube headers, if they'll fit in the engine compartment, or large outlet Magnum manifolds if they won't. In a light car like that, a factory high-stall 904 converter should be adequate. Keeping it simple.
