IF it has the 258 bolt pattern the usual AMC engines will fit. 304 or 360 V8s among others (I doubt if you want bigger than a 360 but they're out there). A 360 Chrysler Jeep engine will not fit. Chrysler did use the AMC 360 blocks for a while though I know the 91 Grand Wagoneer still used the AMC 360. Not that it matters but the AMC 4 cyls use a GM bolt pattern and won't fit. <img src="/forums/images/graemlins/cheers.gif" alt="" />
