Carl, I'm tinkering around with the idea of building a "216" that's actually got 266 cubic inches, has 9:1 compression, replaceable rod bearings, 30+ PSI oil pressure at hot idle, and doesn't leak oil out of the bellhousing. It's also going to be impossible for anyone to tell it's not bone-stock original! I'd love to build up a demonstration rig with my bellhousing dyno on a trailer and haul an engine like that around to various car shows, antique vehicle meets, etc.
