Has anyone heard of a preproduction ls1? The casting on the block has a date code from 1994 and the valve covers has the coil packs cast into the covers. The crank has a stamp number:12552840c.
If anyone knows what vehicle or what this motor came from, it would be helpful.

Yup, there were 2 different threads where users here found prototype lsx engines. They had detailed pictures of the head castings and some other things very different from production models.
I don't recall them having coils cast into the covers though. Got any more pictures? Seems really cool

These type of things pop up. There was another post on here of a set of pistons a guy bought off of fleabay. They were listed to be a replacement LS 4.065" piston. He had pics up, and they were prototype DI pistons. Weirdest looking piston you'll ever see. Things that make you say hmmm...
