Just recently had my XP wagon registered for the 1st time in over 25years. During rebuild installed a 4.1 from an XE (see wazzas XP wagon thread). When I got RWC, had no probs at all & absolutely nothing said at the RTA either when I got the reg done. The guy doing the RWC was well aware what the engine was, not sure the RTA guy even knew what AN engine was.....
