Hello everyone. I am the proud owner of a 2009 silverado and I'm going to be doing a 4.8 to 6.0 swap. So I'm in the hunt for a LQ4. I already have 243 heads so if someone just has a block for sale that's ok too. Thanks for your time

 

You are better off looking for a GEN 4 6.0 instead of a early 6.0. There are alot of changes between the years.

Knock sensor placement, cam sensor placement, timing covers, 24x crank trigger to a 58x crank trigger on GEN 4 computers like your silverado.
