Too much compression

Response to Wooo LOOK at thaaaat piston !!
I agree on the compression. I'd try to keep the compression closer to 8:1. Those older heads were low turbulence, unlike the newer Vortec style, and won't tolerate cheap fuel with high compression. Timing should probably be 32-34 degrees MAX. Make sure you're not running lean. 10:1, you better be bringing 93 octane to the dock.

Detonation beats the bottom end up too. I like the RV cam idea..more useful power (torque!) at cruise. Now a pair of 350's will fall right in there, and you can run those 327 valve covers to fool everyone.
