Ask your engine builder about this, and find out of you need one of these oversize rear main seals...

I have line bore and line honed thousands of 350 block over the years and unless we are putting on a billet rear cap I have never touched the seal area. 400 blocks are a different story!!

I have never in 38 years of building engines ever offset the rear seal in a block before.

I MUST BE LUCKY!!!!!!!!!!!!
