WOW, you have a great combo to start with! Textbook!
All 3 cams are too big for a street set up, Unless your compession is bumped up. I have the 274 right now. It is big for the street! It can be run and driven on the street but the power is on the top end. You need a small cam for the street, We ALL think or thought a bigger cam will make more power.........top end.
Go with the Extreme 262!
