Brought A 78 F-350 Flat tray ute-Duallies-IN Queensland Australia East Coast. 4 speed Manual. The cast Number is D2AE-OA large circle embossed then another O after that, 1982 Crapper, somethiing about cast shifting There appears to be little correlation between the XE in the cast number and the XE Falcon model except that the two appeared concurrently on the scene. Apart from thicker bore walls, the XE blocks had thicker pan rails. Unfortunately, there was a problem and the casts suffered from core shift, to such an extent that Ford U.S. rejected them as unsuitable and left Ford Australia with them. Now Ford Australia, never being ones to miss an opportunity simply used the blocks and stuck them into passenger cars and trucks where the core shift problem was not noticable under normal driving conditions. These blocks have acquired some mythical status, but some accounts show that, as proved by Ford U.S, while the extra metal may be handy, actually benefitting from its presence while building a hi-po engine can be problematic.
