No thanks to the machine shop and milling anything. That's for when this guy has a spare 340 block :)

The only thing I come back to is cam choice still, esp with knowing now that the block is 30 over. I over think this stuff to much.

Ps I'm now loaded up on liquid gold...aka brake cleaner

Oregon Cam Grinders has their version of the 68 340 cam. That's one you might think about. @krazykuda Karl can tell you about it. He had a hand in getting them to offer it. Nice, reliable, slow ramps so you can have trouble free operation everyday.
