Re: Pinging
Yes, unfortunately you are looking at a complete rebuild of your 427. With todays oils a roller cam is the best way to go, but that cost alone is close to $1000.00. If you go with another flat tapped cam, I would suggest a name brand over a generic cam. Since this engine is in a C60 you will have to stay conservative in cam selection, but you can still upgrade some from stock. I would suggest calling or emailing a few cam companies and ask for their recommendation. If you do stay with a flat tappet cam, proper break in is of the utmost importance. If not followed to the letter, you will be right back where you are now plus a bunch of money down the drain.
