yeah, my 216 only lasted 35 years or so without being blueprinted.
LOL...yeah, I've had a number of long-lasting engines built with factory specs. Apparently, not all OE engineers are stupid.
I understand the desire for close-tolerance work in a racing situation, and the theme still seems to be that some sort of "blueprint", or guidelines, are followed. But I think that's a very small fraction of rebuilt engines.
