Your confusion comes from the Haynes book.....not a real good source of info.
In 1986, Chevy changed from a two-piece rear seal to a one piece rear main seal. IF your block is a 86 or newer, it has this plate in the attached picture that LT1 spoke of. That plate holds the seal and is attached to the rear of the block. This seal goes on after the crank goes in.
If you have a pre-86 block, it has a two piece seal and one half goes in before the crank and the other half is inserted in the rear main cap. Make sure on either seal style to turn the seal lip INward.Last edited by robot; 01-29-2007 at 10:32 AM.
