SBM 340 Rear Main Cap

OK fellas. This is not a parts wanted thread even though the OP (new member) asked in his opening post. DO NOT sell him parts on this thread. Send him a PM.

I have a 340 block with no mains. I was hoping I could use 318s. My machine shop just informed me the rear main is too short.
Nobody makes one. Anybody have any suggestions? At least, any help on specs and dimensions to have one made?

First post, have mercy, thanks

@ronmonger, we do not ask for parts in any threads but Parts Wanted ads. Apparently my hints about starting a wanted ad has gone unnoticed.
