6.4 l. ?

[MMeier]

Anyone hear of building a 6;4 engine from a 6.7 ? If so, how, 5.9 crank and internals ??

Blacks diesel performance sells them. I'm not entirely sure how they build them though.

The way I understand it, it is a 6.7 crank in a 5.9 block, then they add a deck plate between the block and head to raise the block height and use custom pistons. They also make 6.1's, same combo without the deck plate. I don't know what fuel system they use, P-pump or CP3's. The sled pullers use them. They turn some crazy RPM's.
