Tranny/tc length info needed

[77crewcab]

Okay guys I need some trans/tc combo lengths. I am putting a 350/700/208 in my K5 to get it running but have decided to put the CAD500 I am building into it in the future. I am currious if I can reuse any of the driveshafts when I do this. What I currently have is a 350/203, and a 700/208. I am thinking of either a 400/203/205, 400/208, or a 4l80E/208. Can ya'll help with the lengths of these combos? Any chance the 203 and adapter fromt he 350 can be used on a 400 if I go with a doubler? Thanks!

ill the best i can.

first off the 203 adapter and case wont work from the 350 onto a 400. the 400 uses 6 bolts the 350 only uses 4 also the spline count and size is different.

im kinda confused by all these numbers and combos so you have a 350/700/208 in there now? if thats the case. very doubtfull they will work for a th350/203 set up. that is probably the shortest auto set up i can think of. the 400/208 might work. its about the same length as a 700r4

also some of these transfercase have different type outputs on them. the 203 i had had fixed yolks where as like a 208 will have a slip yolk in the back. i swaped from a th350/203 to a 700r4/208 and none of my driveshafts worked

Sorry for the confusion. The K5 currently has a 350/203, I am pulling it and replacing with a 700/208 just to get it driving. When I swap in the Caddy I am looking at putting in a 400/208. But honestly I guess it won't matter much because I will just need to get new shafts made. I was just trying to figure out the lengths of the different combos.
