I've read all of those ..opinions.. myself. I have that cam in a alum. head 383 with quality parts thru-out. The motor maybe makes 450-475 hp in a '68 Coronet Boat. I had a low stall converter which made the car unfun to drive. I called Andre @ Edge racing converters and gave him the specifics. He built a 3000 stall for me. It's great from a dead stop and it is civilized in traffic. For a boat it is surprising how strong that combo is and it just keeps pulling. Before with the 2000 stall it was ugly from a dead stop. I like that cam with the correct converter I also run 3.55's with 29" tires.
