Hey, i am looking to swap out my blown 283 I6 with a new motor.  I am hearing so many different things and am gettin a little pissed with the chev guys that like blowin motors in the mud.  Jeep folks i need your help.  I am looking at the 302 or 305 but have been offered a 400 pushing 450 hp.  Any help you can offer would be greatly appreciated.
