72 340 build vs...other options

Did you have to align hone it?
No sir, it did not need it. The block has dyno time only coming from a big shop.
I got a 0.040" 360 with a spun rod, wouldn't mind making into a poor mans 340.
The problem is getting a 340/3.31 stroke crank into the larger journal of the 360. As Newbomb Turk stated, he called up Bill and there not being made anymore. Dang shame.
