alrite fellas,
what sort of cam profiles can i have with standard pistons in a c20xe? was going to run qed 420's but ive been told that when your revving close to 8k the valves touch the pistons and make a mess of the engine as a mate found out first hand. later on i want to add some direct to head tb's aswell. so what cams have people used with out having pocketed pistons and what sort of revs were they going to?
cheers guys any help would be appreciated.
