Now the quandry of picking a cam for my blower motor?
I was reading up on blower cams and see that they should have, well here it is from the Summit site.

"A supercharger can overcome inadequacies in a stock cam up to about 4,500-5,000 rpm. You will typically find that performance with a blower will not be significantly enhanced below these speeds with a cam change. However for optimum performance at higher rpms, a more aggressive cam will provide substantial power increases.

For best performance with a blower you should look for a cam that has higher lift and longer duration on the exhaust side. Street performance with a blown engine is usually best with a cam that is ground with a 112 to 114 degree lobe separation. Blower cams can be typically run "straight up." Note that a blower has tendency to lessen the rough idle of radical cams."

Looking at the FWD F2 cam?
260/260 duration at .006 tappett lift on the intake/exhaust 467/467 gross valve lift on the intake/exhaust centerline 114
Can FWD grind a custom cam?
