You can buy an adaptor to put an older two peice rear main crank into a one peice block.I'm going to run a one peice rear main engine myself,i'm not sure about the rear main,i think it eliminates the leakage between the rear main cap and the block(easily fixed with silicone)but i think is more prone to leak out of the actual seal 'cause it's bigger diamiter(turns faster=more friction)

I'm building one myself, the flywheel bolt pattern is different(smaller), the flywheel is weighted and the rear seal is different. Bearing sizes and balancers are the same as the older stuff.

We ran one of these last year. It did well until it broke a rod bolt, and then the whole block pretty much shattered. It does take a different flywheel (I have a lightweight (15 lbs) corvette flywheel for this is anyone is interested), as well as the oil pan. Oil pans are a little hard to find so we ran a stock pan and accumulator. I think that was about all difference wise. It did leak a lot of oil though. I am guessing I didn't get the rear main seal put in the housing straight. Oh well.

Oil Pans for one piece rear seals are easy to find if you know where to look.Champ Pans(champpans.com)by JR man. makes a great product and will ship to anywhere.
