You're right on with that one with the hydraulic rollers being vastly different from their flat tappet counterparts. Light switch like opening when compared to even the most efficient flat tappet grinds. Comp shows a 110 LSA on their website, but it's that 38 degree ABDC closing that makes it such a forgiving piece. I didn't think about it until I looked at the cam card at the bottom of the page and the 110 LSA, but a question for Rusty. Do you think an additional 4 degrees of advance would make it a little more goal friendly with off idle power?
