LS1 Aluminum 5.7 with forged rods and pistons, all new with a 4l80e trans. T-case rebuilt by Overland Cruisers (local to me). Extended range 36 gal. tank, new driveshafts from Tom Woods. Should be a hoot! Now it's carpet time, couple small spots to deal with on drivers floor, otherwise this is a super clean rig with only 134k original miles, seats are still mint. It's been a haul, I work for a while and lose steam and it sits. Now I can hear it rumble and it's game on!
