Stroked 340 vs Stroked 360

I thought a bigger bore unshrouds the valves more for a slightly better flow into the combustion chamber. Smaller main bearing should make for a slightly lighter crank. And you have 8 more cubic inches. I think theoretically those all are a benefit. How much?, seems to be very small, but each one is a tiny improvement.

I paid $200 for my std bore 340 block. Easier to find at the swap meet than a 360 or 360 LA roller block. There was another 340 block for $300 at the same Spring Fling swap meet.

Rod journals have a larger swing (reciprocating) weight on the crank. And can allow lighter rod too. So any weight there is more dramatic than in the center where the main journals are.

Would be cool if Scat made their cranks across the board with Chevy 2.100 rod journal style so we could run Chevy rods and save some money.
