Many thanks Stan. I can definitely use that information. I have been curious how a higher ratio 1.7-1.8 rocker arm might work with the spc-8. Looks like 1.65 to 1.8 gained about 3* @.050 and about 2.4*@.2. The big rocker will make the variable duration effect of the Vpros more pronounced. With the solid lifter like performance the using vpro’s the cam might really run with those bigger rockers.

The spc-8 cam we have has a little less acceleration. That looks really big.

Jay,
I will have to figure out where I got those base numbers from. Can you share what numbers you have?

Thanks,
Stan
