It's a custom regrind from Oregon cams. I needed to utilize some springs I already had and they were small single Comp 942. I had them new. They were left over from a project that I didn't complete years ago, so I used them. They needed low lift and that's fine with me. Less stress on everything. So the grind I settled on is .465 lift and 250 @ .050 duration ground on a 108 center line. I had to go big on the duration because of what happened to the cylinder head. It was "accidentally" milled like .180" and got compression way higher than I wanted so I knew to run on pump gas I needed something pretty stout duration wise. It turned out really good, much to my surprise. lol
