We will be using a 744 profile as that is what the rules require.
The 041 cam within the confines of our rules and max compression for an SD would actually hurt it. That has been one of the current problems with the SD's. To much .050 duration for the compression.
Pontiac needed a cam half way between the 068 and 744 in duration for the HO and SD. That would have been perfect in conjunction with their compression ratio's.
