Yeah, the cam is suprisingly small. The motor has a solid lifters and shaft mount rockers that are a bit noisy. It sounds like a sewing machine with the hood up. I could swap to hydraulic lifters and still make 800+hp to the tires.
It had a loud external fuel pump before that was a dead giveaway that it was fast. The twin in tank pumps might be the best change I made. You can't even hear them now.
