727 4 pinion planetary....

I thought by 76-77 that everything had gone over to lockup converters already?? I will defineatly be looking closely at the slip splines for the drums and the bushing diameters... I would end up re using the planetariy ring gear and the planets as an assembly, I mainly want to swap out the output shafts and the tail housing onto the rv trans and build that one up... not planning on mixmatching parts too much unless I have too... also never hurts to have parts kicking around...

will definitely be putting in a bolt in sprag regardless of trans abuse lol, haven't decided on a tci or spending the money on a billet coan unit..

Forget Coan go to TCS in Langley BC they carry their own billet units in both steel and aluminum and include the 24 spring return module in the price , I put a steel one in , my 904 along with their race rebuild kit been back and forth across Canada with no problems 524hp/527tq . you can find them at tcsproducts.com .

PS their Mopar guys and race a 1400hp car of their own not a bunch of chivy guys trying to make a few bucks on the side .
