Within the confines of the rules Paul's SD can make it to 9.5:1 and that seems to be area on the computer where the 744 cam starts to work well. If you want to stick with a pump gas motor and have that cam work the 9.5-10:1 range seems to be a honest location to start from what we have seen.
Wolverine and Melling have been our best picks for over the counter items. I have Mellings in several cars.
One the RA IV's we have dyno'd everyones RA IV option and they spec out on paper the same usually but not in the motor. So far the Melling has been the best option there.
