power guess and intakes
There was a PHR story by Vizard about 4 months back. His 492 street motor made 656 hp on a street roller. He made a big deal about having to get the lobe seperation angle right.
I also heard that Vizard had tested the Darran Morgan intake and found 20 top end hp on a motor of about 600 hp over what was supposedly the best of the rest??
