LS7 main bearing problem
Does anyone know about mains having to tight of clearance on new LS7 crate motors? A local dyno place told me I might be smart to check main clearance on my unfired motor! He showed me the block and crank with seized bearing fused to the journal. It was the middle bearing as with others he knew of. Any feedback appreciated especially any GM people out there.
I'm concerned about warranty issues as time from purchase to running the first time can get long.
