greetings everyone


we have a 427 and a 454 ( procharger at 13 psi) that are eating camshaft and lifters.

we have tried diferent springs, lifter brands and lastly a solid cam and lifter combo. NONE worked. The funny hthing is the NA 454 is OK after many passes.
Do you have an idea what could be happening?

thanks

My best guess is theres no much metal to metal contact.

Do you have a suffecent oil supply? Dry sump or wet sump system?
