Engine Block Casting 6.0L
 

I just got in to our latest project and removed the alternator to find a 6.0L block casting # instead of a 5.7L in my 1999 Trans Am. Can someone please help me to identify what this engine is out of? I have no idea where any of the codes are located at.


Please help!!!

This is on the left rear of the block one right behind the head and one on the side


The 5.7 Liter LS1 engine has two locations where information is stamped on the block to identify the component. Location one (1) is the primary stamping location. Location two (2) is the secondary stamping location. Both stamping locations contain the engine identification numbers.

I cant remember if one is a vin if so post it and ill run the viss to find out what it is from.

Is the block cast iron or aluminum?
