Does anyone know the differences in length of these transmissions? Im tring to figure out what driveshafts to be looking for. The truck has a 465 now so what if I go to a 700r4, or to a th350, or to a th400?

Thanks guys.
 
i have measured those combos to be the same length also but the adapters are what makes it that way

I have heard this before too.

I know for a fact the '80s combos are longer.

Maybe Watson will chime in here, he's the expert.

the combo i am talking about was from an '81, i have been wrong before, but i am pretty sure my mind was not playing tricks on me now. it was a 465/205 w/ fig 8 pattern & was 10 spline

are there 2 different versions of the 465/205 combos besides adapters being round or fig 8? are the legthss different on the 10 & 32 spline models?
 
My th350/np205 was stock. The SM465/np205 came from another 1st gen. The factory set it up so the crossmember and driveshafts were the same. That way either trans/ TC would go in the same place.
 
Yes. One 465/205 adapter is 7", one is 10". I posted which is which, do *I* have to go search for it? /forums/images/graemlins/tongue.gif

My 87 had a 465/208 and I swapped in a 86 th400/208. The adapter seemed to make them the same. I used the origional cross member and drivelines withought modifications,,,

I think the rear drive line was about 1/2 inch off. Pretty damn close though...
 
Yup... Im another one had a 79 TH350/205. put a 10 spline sm465 in its place and the cross member lined right up just like it still had the TH350 in it.

I swapped a th350/np205 to a sm465/np205 and used the same driveshafts.

I may perform same swap, if I manage to get all the parts, but if not, I use a TH-700. What happens to shafts?

edit: Found some measurements from the web... Do I need to shorten the rear shaft 3 3/4"? And lenghten the front shaft same amount?
 
i don't know the measurements but u are right u will need to shorten rear, & lenghten frt. if u are doing it to a k5, & u have much lift u may need a rear cv shaft.

No lift, stock height. Law allows only 2" of lift, so I guess I won't have any problems with rear shaft.
 
if u use a 208 t/case which is the most popular t-case that comes behind a 700r4, u will need a new rear shaft. it will need a slip yoke & a cv, but due to the lack of lift u could get a stock one. /forums/images/graemlins/thumb.gif
