Found this site doing my motor swap homework. Im working on swaping a lm7 from a 2000 silverado into my 96 sierra xcab. Almost got old motor out so far. New 5.3 engine is in garage waiting for me it was a junk yard find. I have motor mount adapters from trans dapt, and Advance adapters flexplate conversion kit, so far for swap parts. Going to use sspwiring for harness and pcm stuff and street and performance for the small stuff. will post pics when i get motor out hopefully this week.
