Anyone running high 9's on the engine. What's your camshaft profile? Assuming it's a roller.

I'd be indebted to you if you tried this cam.

Little shy on the lift, but duration @ .050 looks close to what I think I need.

How many cubic inches and what compression.

 

[lenweiler]

420 cu.'s and 13:1 cr. Heads flow 345 cfm.

Damn, that's what my new heads flow and your going 10.30's.. Kind of exited right now.
