I know that you convert the 351W two piece rear main seal to a one piece through a machining process..My question is, what do you do on the 460 stroker engines that you sell that cannot be converted to a one piece..What master engine builder secret if there is any to make the 460 from having a rear main seal leak..I heard of rear main seal crush as not to be more than 020 to .030 total crush..Any more and a leak will develop.. Also I heard that line honing the block and there is even a bigger chance of developing a leak..
