So I have a 2008 avalanche donor truck with a Lc9 in it. My 2009 Silverado LH6 has the dod/afm delete with a cam, ls7 lifters, pushrods, valve springs. I thought a lifter or the cam failed recently getting a weird squeak at idle then around 2000 rpm it started to sound like metal on metal. I pulled the heads off expecting to find a damaged lifter and cam. All lifters look fine and cam looks fine from what I can see through lifter holes. Realizing that wasn’t the issue I’m stuck on what to check next. If it is bottom end I have a lc9 like I said above that I could put in with all of the goodies from the motor that is “pooched”. Is there any reason I cannot swap the lh6 out with the lc9, or does anyone know what I should inspect next before swapping motors. TIA.

As long as the crank reluctor wheel count is the same it should be an easy swap.

If the block isn't toast, the LH6 block is pretty sought after for high HP builds and sleeved stroker set ups. Don't just scrap it, sell it.
