Unhappy turbo 400,700r4 swap

I am planning on installing a turbo400 and 3/4ton rear ends out of 82chevy 4x4 into my86 1/2 ton 4x4 with a 700r4. the 86 currently has a turbo 350 with about a 2"adapter due to the 350 being shorter.The transfercase and the tranny are held together with 4" studs needed when using this adapter,the nuts come loose and the studs studs snap off at the tranny.In order to put the 400 in I believe I will have to move the crossmember. It appears to be different from the 86's location.Will my driveshafts out of the 82 be the right lenth? Any answers ,suggetions greatly appreciated.

YOU HAVE MORE PROBLEMS THAN THAT WHAT ABOUT THE DIFFERENCE IN OUT PUT SHAFT SIZE? THE 400 4X4 IS REAL CLOSE TO THE ORIGNIAL 700R4 LEGENTH,AS FAR ASTHE CROSSMEMBER I THINK YOU CAN MAKE IT WORK IN THE SAME HOLES, CHECK THAT SHAFT SIZE FIRST. GOOD LUCK.

Question

Why would the input shaft size differ?The 82 is acomplete wrecked truck minus motor,frame is bad.The crossmember holes on the 82 is about 2"farther back than the 86 the crossmember deffinately is different.Is the engine on the 86 in the same position as the 82?or is it farther forward?Thank you for your comments

Cool

what toymoble is yelling at you about is .... the T-400 will not bolt up to your current 4x4 transfer case where the T-350 is bolted.


The T-400 out put shaft is LARGER than the 350/700 output shaft.

I can not answer your questions on the drive shafts etc... sorry.
