So why would it suck in a smal cube motor if comp says it recomended in any 5.7 to 6.2? Just because COMP sells cams, doesn’t mean they’re any good at specing them. that cam will work, in that it will open and close the valves, but it is in no way even close to a good working cam. > [@FS: Eboost 2](https://forums.speedlife.net/t/fs-eboost-2/40807/3): > > I was just curious, because I am scared I will have to flycut the stock pistons too much. I saw SK didnt have to flycut his with .600 lift so I got my hopes up that maybe it was possible. It’s not lift you need to worry about, it’s duration. Esp duration below .200 lift. That’s when the valves are in closest proximity to the pistons. by the time you reach max lift, the piston is quite a distance away. --- _[View the full topic](https://forums.speedlife.net/t/matts-2005-gto/204608)._
