Brainstormin' 440 vs 5.9 ...

I don't see this as a fair fight. The 440 is going be a lot faster than the 5.9 especially if you deck the 440 block.

Pistons are around .156" in the hole on those engines. I've decked .100" off of dozens of them and installed a decent cam.

They really come alive when you shave the deck down and get some compression in them.

People shudder when you talk about milling .100" plus off blocks and heads, but stack it up on a feeler gauge. LOL It ain't a lot when you're talking about structural integrity. It sure does help compression, though.
