Is anybody running the Thunder Xtreme 227/227 XTR .639/.639 116lsa ?
TTT. I would like to know myself,and how does it do compared to a Tr224
its a single pattern cam just like a 224/224. its going to make more power, but not a real lot. the 227 does have a high lift. its not a popular cam, not many guys are runnin it
