rebuilding a 1990 mustang 5.0 HO engine.?
I have a 1990 mustang engine and it needs rebuilt. There are many rebuild and rering kits but i am not sure on which to purchase. Some ads on ebay say the kits are for 86-89 or 91-95, but i thought they were all the same from 86-93. Please help me figure
Disregard junky's reply. You can't "believe." You either know or you don't. 1986 factory Mustang engines have a flat top piston with no valve reliefs cut into the pistons. 1987 through 1992 have forged flat top pistons with valve reliefs
