Re: 440 6 pack
The reason to fill blocks is to preserve ring seal. Increases rigidity. Fill as high as possible leaving 1-1/2" at the top.

Re: 440 6 pack
Is .171 on thrust side of cylinder.
That is the most significant spot.

Re: 440 6 pack
I would rather see it on the bottom than the top
for the thinner side. My big blocks are thicker than that by .030/.040. I think you would be fine with a filled block at that dimension. Sometimes my filled blocks leaked better after they had been reringed once....But they were still decent the first time.

Re: 440 6 pack
Does anyone know if it is legal to put 4 bolt main cap in?
The type I'm looking at bolt through the side of the block. |

Re: 440 6 pack
Nope!
Really not needed in a Mopar 440 at this power level in my opinion.
