I knew it cranked over funny, and it sounded like no compression. Its on one of our builds we did a year ago. An LS7 with cam, and a blower, it made 715 at the tire, and the old Guy has been driving the crap out of it. Yesterday getting on the freeway, top of 1st the chain let go...

. Then nothing. Been working on LS motors for 12+ years now and haven't seen this before. The chain and gears are JP performance stuff from Australia, but shit happens.
