340 Rebuild "Musts"

Nope. It's a street car any sissy could drive every day.

I'm still trying to figure out how you get 10.5:1 compression unless the piston is out of the hole. It's not possible. For Christs sake it's even in the Chrysler book. Unless you cut the piss out of the head.

And then we can discuss lowering the crevice volume.......

If running iron heads he won't want 10.5:1 compression on the street. That is why I recommended 9ish:1 for pump gas. This allows him to have a safe combo that won't detonate with a bad tune. Most novice guys are just learning to tune with timing and carbs. That's why I gave him a good starting point for initial timing,full advance and when to bring it in. I just went thru all this with help from members here. I was only trying to help him get a fun combo without overwhelming him with crazy combos. I do see the validity of your thought process but this guy is starting out. Not building a pro stock engine. I have a buddy running a 340 car with a blower making 9lbs of boost on stock iron adjustable rockers. Makes plenty of power and rpm. Still running strong.
