Trick Flow 440 heads, The Real Deal?
Look at this way, deduct 1 point of the compression ratio for being aluminum and another for a big street cam/little strip cam. It is large enough to bleed down some of that ratio making pump gas do-able.
I have run 11-1 with a slightly smaller (248@050) cam & 93.
10-1 iron headed on 93. Same cam as above.
If the cam was smaller, I'd call it getting into the "dangerous territory."
