What you might not know is all of the 1993 to 1995 LT5 motors were built in 1993. The last engine built was on Nov 21, 1993, at 1:30 P.M. and the last four of the engine number was 0003. Hows that for obscure information. Kevin if you would like to know anything else about the LT5 motor I have a lot more. Like what was the broom stick used for in the delicate measurment on the LT5 motor at Stillwater, Oaklahoma, home of Mercury Marine.

Mahle was the piston manufacturor. In fact they are still in business and make a nice replacement LS1 piston. Birmal is the head manufacturor you are looking for.

Birmal got out of the LT5 cylinder head way before 94.
