Anyone got experience with running over 11:1 on pump gas with the MP 590 cam in a big block (aluminum heads)? If so, what's the CR (and did you measure or guess), what's the installed CL of the cam (I think straight up is 104), what max advance did you run on ignition, and what was your cranking compression gauge reading?

Other pertinent details on you combo would also be appreciated.

Race gas blenders / octane boosters / E-85'ers need not apply, I'm looking for guys running straight 91 or 93 AKI pump gas.

Thanks!

Scott
