11:1 too high for pump gas?

I don't like anything over 9.5 to 1 on pump gas. That is plenty run what you need for performance on the street.

I have gotten away with a half point more in iron heads and 11-1 with aluminum. A point drop would be a bit friendlier as you could ping easy with something being not up to par (fuel) being off or broken. Like a vacuum line leaking or distributor malfunctioning.

I agree, flow over squeeze on the street. The cams I have used in the slightly has their ratios were big for the street bleeding off compression.
