How does cam timing affect power with the Whipple system? In other words, using an HP500 carbureted kit on a 540 ci engine(stock cast iron heads, 7.5:1 compression) , would it be better to stay with the stock HP500 cam timing or would using a blower specific cam make substantial gains in power? Does the blower move any air at idle speed to help smoth out a radical cam? Thanks for the advise.

Harry,
There is a lot to be gained in camshaft design on the 500HP Carb engine, stock cam is certainly nothing special. If your going to a 540, the carb should be changed to a minimum 1050cfm. So if your building a 540 carb engine, you should change the camshaft to a much more aggressive cam design for the SC. The screw compressor will idle far better than any roots, so you can go very aggressive with the cam.
Thanks
Dustin
