I'm Awesome
24x, GenIV rods and pistons, knock sensors in the valley, no DOD or VVT. 4 bolt DBW throttle body on an old style truck intake that has the newer style TB flange.05-06 was a weird transition period and I'm not even sure if they were Geb3/4 or a little of both. I know they were getting their ***** kicked trying to get a muffler that wouldn't sound like ass when in AFM mode like the 07-09, those for sure had LH6 motors. But an LM4 was low come, early heads. Is it 24X? Gen3/4 rods?
