Yes. All of the GM small-block engines are descendants of that engine. Somewhere along about 1990 they changed the rear crankshaft seal. I'm not sure what has broken compatibility since about 1995 'cause I don't have one - but things like the intake manifold, distributor, water pump, etc from a late '80 will bolt onto an 1955 engine. Obviously the crank and pistons are not the same 'cause the displacement isn't the same. -- Philip, with 4 of them, none stock. _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
