Right now I don't own an LS powered truck, but I'm working on an idea for an AWD T-56 6 speed LS2 Jimmy or Blazer. I won't go too crazy on the mods like I'm doing with my GMC Syclone modified for Time Trial events. Over this Fall/Winter I'll be installing an all aluminum GM Performance 4.3 V6 turbocharged motor.

You might get a kick out of these Thunderhill Raceway track day photos here:

Here's some on track action at the 2007 SCCA NorPac Time Trials:
