I bought it and now am not gonna use it. I have all the hard parts for a 454 and am gonna build that instead of screwing around getting the 350 going. Since I was all ready to build the 350 just so I could see what the cam would do I'll install it for whoever buys it. Within reason of course. *will not fly to Kentucky* I paid $235 for it that's what I want for it. Along with the normal gasgets and such +.100" push rods are needed with this cam and lifter set. To be used with stock rocker ratio.
