I just recently bought a 04 limted auto XFIRE and i love it but would like to get more power out of it. My question is how hard would it be to drop a SRT-6 engine into it what all modifications would it take? and i would like to know if you guys know any mechanics or dealerships in thr oklahoma, arkansas, texas area that are competent with XFIRES for the swap and or regular maintenence.
