Just wondering I don't know much about B block mopars and their limits. I'd just like some numbers to chew on thinking of going with a B in my next project

4.375x4.25 seems to be the max with a stock block 400. That combo uses a 6.5 Shivvy rod. 512 is the biggest MM builds because any bigger and the stock block becomes a grenade. An Indy B block I think ive seen someone somewhere build a 4.5x4.30 out of one of those.

My engines a 400 block 4.402x4.250 for 517". All the cylinders sonic checked ok, but it did take 9 blocks to find one that would work!
