Vital stats from some later model Grand Nationals: 200+ HP at around
Great sleeper musclecar engine, maybe even better Jeep engine... enough HP to pass people and cut through the aerodynamic disadvantage... better low end torque by far than the 4.2... a turbo and nice aftermarket and OEM parts options (Including an intercooler for the last year of the GN)...
Motor is a decendant of the Dauntless V6 Jeep motor...
Talk to Advance Adapters. One of their catalogs mentioned a solution to put a 3.8 into a Cherokee, but they were probably thinking of the naturally aspirated version at the time. Don't expect a kit, or a series of detailed instructions. Why not a Pontiac Grand Am or Grand Prix engine instead? I think you could get those supercharged, thereby avoiding some of Bill's objections.

;^) I think one of the attractions of a V6, is the weight factor and the perception that there will be lots of room under the hood. This in theory will make installation and handling easier than a V8. However, you have to look at the fact that the V8 transplant has been done at least hundreds of times, and you can find all the problems and solutions discussed ad infinitum on the Net and elsewhere. If you really want a V6, the 4.3 litre GM V6 uses the same bell housing pattern as the V8.

Um.... something seems to be *missing* from that list ... ?
