904 Identification

2500 stall would be the minimum, I would recommend 3000 stall. Not sure what you're cam spec's are and that makes a difference. Also, tire diameter is a factor, not width. 65'
Diameter is gonna be 27”-29” not 100% sure yet. But the cam specs are .465 Intake/exhaust, ADV duration 270, .050 duration 221, lobe center 108, the isky webpage has it rated 2000-6200 rpm range.
