Looks like I'll be getting a 340 resto block for the project so that narrows the choices down to the 340 main size.
K1 has the 4.125 and Callies has a 4.250 Dragoslayer so those seem like a couple of good candidates to use. Probably go with 4.040 or 4.060 bore size but I'll wait until I sonic the block before I make a decision there. I'll want to stick with a bore size that has a lot of ring choices.
Anyone have any other crankshaft options that I should look at?
