I always thought it was the regular 4.25x4.310 but I have never taken 1 apart either. I know you can't take the genV and VI 502 blocks to a 4.375 crank, so I wonder why you would be able to do this with the 454 block.

Who knows. My 496's are built like yours. I havn't run them yet because I don't have anything to put them in right now they are collecting dust.

Happy new year. I am on my way out in a bit.

Probably a pretty big cam, but it is not impossible

KNOT-RIGHT

When all else is equal there is no replacement for displacement

The right combonation goes along way.

Agreed. That is why I use 582" engines at every oportunity.
