I never heard of warped new cams until now but then again , I never saw a cam broken in two until I opened my new Mopar Performance cam from within it's shipping tube and found it busted. Now that also is a confidence builder !!!!!!
I know, I always brought the block home from the shop and put it together and never had any problems. I guess now days they don't put fragile or anything like that on the packaging and just shove it through the mail.
