Edelbrock aluminum heads

I agree...we spend all our time driving under 3000 so that's were you want power. I have also used the old .474 purple shaft with about .238 duration and like all big cams it was a dud on the street. Those cams make power at high rpm and are a necessity for 12 seconds at the strip, but require hi stall converters and gears which are unpleasant for normal driving.
