Re: Removing Performance? Need Cam Help...
Lift limit depends on if you leave them stock or not. You can machine them to take a higher lift cam, but stock I think they have about a .480 limit. Some year model vortecs are less if I remember correctly, so do some research before buying a pair. Or buy a new set already machined and dressed for a high lift cam and bolt 'em on.
