I run that cam in my GTX, 4spd and 3:54s and it works great. Bottom end and good MPG. Sounds too tame at idle though. My sons running a 509 in a 360 4spd and 3:55s and it has good bottom end to (will ignite the tires with out dumping the clutch) and is a lot livelier than the 484 but MPG is horrible
