Best option for a 5.3 .. I am trying to decide which is the best LS1 option on the 5.3? I am really looking hard a LM4.. Is there much diffrence between the LM4, LM7 & L33 besides a few HP? Or the Flexfuel L59.. I am making a complete install in a 97 Z71 and just trying to decide my best option.....

The L33 comes with LS6 heads and a better camshaft. I was looking for an L33 just because they're alluminum. I lucked out and got an LH6, didn't even know until after I got home. It's got 320hp, 340 tq. I haven't been able to find a dyno graph of a stock LH6 but it seems as if it would make more power than a LS1 aside from corvette or the 03 SS or WS6 versions.
