America's Most Wanted kits.
Exodus
Rubitrux
Dakota Customs
etc
Bunch of places all do the AMW kits.
I got quoted 130k to do Hellcat, 8 speed, 8 lug, 40s the whole deal. Its not that bad, all factory parts, everything new. A TRX is now 125k and if you already have a Jeep...my only complaint on the HC swap is they won't do a stick shift.
The 392 and 426 they will.
