76 Ramcharger 440 efi, nv4500, 203/205 doubler Dana 60 Ft, 14 bolt Rr 42 in. tsl
Im writing this up to make a one stop fact checkpoint. All info I've gathered from various sights and some other sources. I spent countless hours searching the high tides of the world wide web. Finally got a loophole to go through and were makin it happen. I had every company tell me this wasn't possible to achieve. IE (Allstate gear, South bend clutch and quite a few other). I bought a rollin chassis for a very good price and it had an Nv4500 but it was an early case which meant it had the lower 6.34 gearset smaller retainer bolt pattern and bellhousing as well. I actually got around to pullin it all apart and it wasn't too bad. I actually enjoyed the teardown. My 727 was just rebuilt and I smoked it already. So the solution to all the problems at hand. First, the input shaft bearing retainer needs to be swapped, Chevy runs a 6.5 inch shaft and Dodge runs a 7.5. Also the opening is smaller on the Chevy for the retainer so the Dodge one needs to be machined down to fit the smaller case hole. Also the bolt holes for retainer needs to be elongated to match smaller pattern. The bolt pattern for bottom 2 bolts on the bellhousing will need to be drilled through as well. Second, the cluster shaft on the older units are a 2 piece meaning the main gear (4th ) can be pressed off and switched to accept the Dodge input shaft. (38 tooth for 5.61 Dodge and 39 tooth for 6.34 Chevy). Third, the flywheel was a pain in the ace to source. Reason being there weren't any 440s made after 74 with a standard transmission. Which means the flywheel has to be rebalanced for a externally setup motor to accept a 12 inch clutch. Mopar Madness out of Colorado was the only one that wanted to make some money cause he made it happen. If you guys ever need parts that are hard to find he's the guy. I've been told the 12 inch clutch from a 1995 and up Ram truck will bolt right up to an older style flywheel bolt pattern. The flywheel should be here this coming week so we'll see. Lakewood 15335 is the bellhousing I will be using. I'm still looking into how I'm going to setup the clutch slave cylinder. Anyone who has any feed back on this topic can chime in.
