[mention]ponchorob [/mention] I just purchased the 236/242 on a 112 LSA from Butler for my 428/455 I’m putting together. Hopefully I can give some first hand feedback on it this spring/summer. The lobes are 3316/3317, though the cam card shows slightly altered advertised of 287 293 vs. comps lobe catalog of 288 294. It is effectively a XR288HR ground on a 112lsa. The .200 intake and exhaust duration is 5 degrees smaller on the Butler grind than Dave’s OF 2.0 cam if I’m not mistaken, with a fair amount less lobe lift.
