Need casting number help
Okay, so I'm rebuilding an engine for my mustang. Problem is, I have no clue what year the block is from. It'* from a Merkur Xr4ti. I know half way through 1986 they changed the specs. That'* why I need to figure out what year and possibly what part of the year my block is from. The casting number is:
Any help you guys can give me would be much appreciated as I've got the block stripped down and can go no further without knowing what parts to buy.
