Possible free cams??
 

I heard about this from a tuner that has some of the wierdest secrets I've ever heard!!! Here's something about cams I never heard of....REGRINDSEXACT COPY of performance cams but cheaper. Technically same thing as having performance ones. Regrinds are cut off OEM cams that have stock set indexing. Aftermarket cams indexed; because sometimes aftermarket companies incorrectly cut off the cam lobe centers or being an aftermarket manufacturer, have more defect products, like body kits. Instead of getting regrinds or aftermarket performance cams, you could swap higher car model cams. Find a higher performance model or model with similar cams, you can swap those in.

He never said what I'm swapping or where I swap them at?? Any idea to any of this?
