Was planning for a LS3/TR6060 swap, engines alone where i live run for 2500-3500$. Iv been looking at LS engines specs and came across the L77 6.0 aluminium Gen4 that came in the 2011-2017 PPV Caprice, it is identical to the LS3 and uses the same 823 Heads (different material valves), Intake, Throttle body, Rods and Crank. the only difference in displacement is the Piston bore, with 4.000 (10.4 compression) for the L77, and 4.065 (10.7) for the LS3.
Also only cost me 1200$ for the Engine, Harness, ECM and everything in the picture.
