3" mains
I think there will be more demand for the 3" main cranks than you might think. Many of us would like to use these cranks in 400 blocks as the 455 blocks are getting pretty rare. There are still a lot of folks who will be building motors using OEM 400 blocks. So you might consider making some 3" main cranks with 4.21, 4.0, 3.75 strokes. Lots of people are having problems with the aftermarket cast cranks, even in mild HP applications. All of us don't have the play money budget that includes after market blocks. I think that overall, the OEM cast 455 cranks are holding up much better than the after market cranks are.
