I am looking for similar information. I found LSx envelope dimensions on the forum, but can't find distances from the 4 engine mount bolts to the bottom of the block and/or to the centerline of the crankshaft.
I am looking for the following dimensions.
1. Centerline of crankshaft to bottom of block where the oil pan bolts up.
2. Bolt pattern for the engine mounts and dimension to the center of the crankshaft
2. Dimension from the back of the block to the bolt pattern of the engine mounts.
Thanks.

I never did get this information. I ended up working around it by purchasing a LSx mock-up block from Summit Racing.
I had my LS3 engine and M6 trans. I bolted the mock-up block to the trans and installed the assembly into the engine bay. I took direct measurements from the LS3 to get a feel for where I had to locate the engine/trans. The LS3 accessories stick out about and inch further than on LS2/LS1 engines. For quick fit estimates, you can use LS1 dimensions that have been posted here on this forum.
