Here's the dilemma.

I could put fresh #62 heads and a blueprint cam and lifter set in. With no other changes from factory config, running 100 octane as specified, my engine should run just like new. Will it? No way to tell until I try.

Or I could spend a couple thou at the machine shop and have the block bored for the first time plus decking plus everything else suggested, along with the fresh heads and cam and HEI. Should it run better? It darn well better, for the money.

Factory stock was a pretty good package. I'd be happy with the power the car should have had the day it was delivered. This car is a cruiser, but I still need to exercise my right foot on occasion.

Numbers matching is an important criteria, and cutting a numbers matching block is not high on my list of things I want to do.
