for what it's worth, I've had no problem with DCR in the mid-high 8's running on 91 octane. (iron heads, open chambers)

yours is 8.15. IMO it's not even questionable.

edit: is the lunati cam card you posted for the cam you have or the cam you're thinking of upgrading to? (to bleed off some DCR.... either should be fine really)

The cam card I posted is the cam I own and am ready to install. I choose it because it has a little more lift that the commando solid cam and close to the same duration specs, just a hydraulic version of same. Hoping for a slight increase in overall performance from the engine using this cam and the LD4B intake.
I was also hoping for a little more DCR than 8.15 but I need to build the engine and I am tired of thinking about it. If 8.15 is the number, that is how the engine will get built and I will worry about DCR on the next engine I build:-)
