Is the LS376/480 an Interference Engine? Would a broke belt or jumping time cause damage, or just continuous stumbling, run failure, etc.?
I did try various keyword searches on Google and here, on "LS376", "LS3 interference", etc. Didn't get any good hits. I'm curious if this engine is interference stock, or if the 480hp version or "Hot Cam" makes it such, with it's higher .525 lift.
