Rumble have you measured cranking cylinder pressure with this cam?
I use the same cam in my 340 and have recorded low cylinder pressures.
Always wondered if it was the cam or other?

Sorry no. This stuff, in general, is in my head as to what is crappy, good, great and pushing it. IIRC, my static is 11.3-1. More than enough on the island. It runs well on 93. I believe I could find more power with more octane. But pump gas was the target.
