: XLR cam swap

11-20-11, 03:49 AM
I did a search for a cam swap on a 4.6L XLR and could not find anything....wonder if GM makes a cam that would give me about 70hp....i might buy a new crate engine and thought i would change the cam and springs and whatever else while it is out of the car.
thanks.....Any suggestions would be appreciated:alchi:

The XLR has four cams and nobody makes upgrades that I am aware of.
