Ford Cummins tranny and transfer case issue
well i ran into a bit of a snag in my cummmins powered 1978 Ford Bronco project.
i originally planned to use the dodge a 518 auto and a np 241 transfercase but have it mocked together and with the length of the slip yoke and the fact that i will have to figure out speedo and a few other issues i am thinking of going to an adaptor and a ford tranny and transfercase.
i have looked into a slip yoke eliminator but apartently they don't make them for the np 241hd.
i have found a adaptor for a small block ford manual, it comes with a new clutch, starter and flywheel for $700 which seems like a good deal to me, remember i am in Canada.
how well do the small block trannys hold up to cummins power?
i am not going crazy but am shooting for about 300-350 hp.
any help would be greatly appreciated.

a np453 4 speed is pretty strong. i wheel with on in my 6.9 and never had a problem. just sometime wish it was a 5 speed.
i would suggest a np435. it is what came in your 78 bronco if it was stick.
the t19 is also a good one, i dont belive it is as strong, since i broke one in my 6.9(snapped tailshaft in half and cracked case in 4 peices)
all ford truck trans with the 4 bolt h pattern have same bolt pattern, same spline count and input length.
hell u could even put a 3 speed on the tree in it.

that depends on if its an overdrive 518 or not. if its an OD unit you can add another like 16 inches to the length of it. a non OD is pretty short, but the OD adds a decent amount of length

you can get a slip yoke elimator for the rear that way it runs a flange. theyre pretty cheap and easy to come by. if you already have all the dodge stuff id just use it its be alot easier and cheaper to make a driveline work than to gave to buy a tranny adapter, starter, trans, transfer and then you still have a driveline to get made.

that is where i am at right now, i don't have the pieces yet, i just have mock up pieces.
i looked into a slip yoke eliminator and couldn't find one for a 241hd only the 241.
i made a deal with the guy for the Ford 5 spd adaptor which will probably save me a bunch of money and trouble as long as the stuff holds up ok.
i guess i will find out!!!
