-----original message------------ " From: "Jim Blair" <carnuck@xxxxxxxxxxx> " " Just had another thought today. Landrover kept the Nailhead pattern and if " the trans they used can be beefed up more than a 42RE The nailhead pattern trans was also sold as the "universal" TH-400. The reason is the nailhead had a deep flange on the back, effectively an inch or so (don't know for sure the measurement) of the bell was made into the back of the block. Theis made the bell on the trans itself shallower, allowing plenty of space for an adapter made by the purchasing company. That's why Jeep, Jaguar, and Rover used the "nailhead" pattern -- and a few others. They could make their own adapter and get the GM trans, cheaper if they didn't have enough volume for a custom case. The old original Dual-Range Hydramatic (four speed) used by Nash and others was made with a separate bell housing like the Borg-Warner autos. IIRC that original Hydramatic bell was cast iron. _______________________________________________ AMC-List mailing list AMC-List@xxxxxxxxxxxx http://www.amc-list.com/mailman/listinfo/amc-list or go to http://www.amc-list.com
