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
