470 dyno test article

I have a new cam profile to test in this engine as well as new valve springs. These new springs are a dual conical spring from Comp with a lightweight tool steel retainer. Total weight reduction from these conical springs is 1 pound. So that is one pound of weight that the rocker arms don't have to move during each cycle.

Nice! Are We going to get high speed/sample video in slo-mo of these in action?:D Just askin'!!
My "Eye-mic" says those retainers barely span half the top outer coil, is that correct?
