Hi everyone, I'm wanting a recommendation on a new solid roller cam for my max effort pump gas 440. Here are the specs on my current setup. Engine runs great on 91 octane and I want to keep it like that.
-440 10.8:1 compression
-2" primary headers
-heavily ported big valve iron 906 heads
-holley 850HP carb and holley street dominator intake
-current cam http://www.compcams.com/Company/CC/cam-specs/Details.aspx?csid=748&sb=2
-4500 stall and 3.73 gears
-3340lb car

So far this engine has been 12.4@108mph at 8500ft DA.( still need to hook up the trans brake)

I'm thinking over the winter the winter ill do a tunnel ram or a victor intake as the street dominator intake I feel is not letting the engine breathe as it needs.
What cam would you guys recommend to make this motor a little more powerful but yet retain 91 octane?


Thanks!
