Check with Mast Motorsports. I think they can give you the information you need to do a DoD conversion on your engine or at least show you the differences between the standard and DoD engines. The other thing is using the J&S Safeguard knock controller that offers group and individual cylinder retard, which is fully adjustable. With the sensors that already come on the engine plus the more accurate control of the J&S, you can get away with pushing the envelope a little. After that, my thoughts would be to barrier coat the pistons and combustion chambers, or at least do whatever it takes so that localized hotspots don't occur. Fortunately the LS has a great piston/combustion chamber combination.
