Putting the T56 Magnum should not be an issue. Since my involvement with Hurst has ended, I'm going to put together a list of where you ALL can get this required items for the swap. This is not rocket science, but you have to stay within the lines. Going outside with require more adapting.
To address the bell housing issue here.
Small Block Mopar (LA) and 3G HEMI is Quick Time P/N RM8074. The bell has a 6.697” bell depth (add .125 for the block plate for total depth) Uses the standard 2-Bolt starter from Mopar. 130 tooth fly wheel must be used.
The top hole of the bell housing will not be used. The starter is located on the drivers side of the engine for retrofitting purposes.
Some of the very first quick time bell housing that allow the retrofitting of the T56 Viper Spec. transmission in our cars featured smooth, un-machined mounting faces. When Tremec introduced the T56 Magnum, which is the TR6060 in hot rodder's (aftermarket form) a rib on the face of the transmission mounting it to the bell housing was not machined off from the factory. The rib remained, which made Ross re-machine some bell housing to clearance this rib. This was 2009 / 2010 time frame and I would assume that these are out of the system by now. If you have an 8074 Bell Housing it may be worth snapping a photo of the mounting face and sending it to Quick Time for verification.
Time to get to work on the details for you guys. At the moment, only American Powertrain will get you about 90% of the way to a complete kit.
Remember - Cutting is required on the E-Bodies. If you are a fan of your virgin sheet metal - step back and look at the TKO kits from the various suppliers or Jamie Passon's 5 speed. Overdrive is SO NICE.
