LS guys are getting full pullouts for $750 and doing entire old school swaps for $1000-$1500
the biggest hurdle for G3 HEMI swaps are the computer and harness
Places like Modern want $1k just for the harness or $2,600+ for the harness & ecu
LS guys out there have the harnesses for a couple hundred and can flash your ecu for another hundred or so
there's power in numbers...
