Hi i'm currently working on modifying an engine block of a GM LS3 v8 5.3L, And i'm working in solidworks 2015.
I did manage to find a file of a block on GRABCAD but it didn't have any internal parts like the pistons, or the cams.
i've gotta animate and do some motion studies before finalizing this modification.
So far the internet has been no help in finding this engine block, or even the engine in its entirety (either/or really)
At this point my company is willing to spend money on a cad file so we can get this project finished and out of the door.
