305 700r4 to 5.3 60E 87 Chevy 4x4 I am trying to get a price for a buddy on a engine swap from a 305 700r4 to 5.3 4l60e.
The truck
1987 Chevy 1500 4x4 Short Bed
TBI 305
700r4
The Plans
Getting a wrecked silverado using
5.3 with stock harness and pcm and fuse box.
4L60 E Will this need to be a 4wd unit because of the Transfer case or will a 2wd work? Also the 60e and 700r4 are the exact same demisions right?
Car shop sbc to ls1 mounts.
Want to stick with all the truck accessories and stock drive shafts.
Main thing Im concerned about is the transmission i need to get the transfer case to work.

nope not the problem. not going to look for the pics but heres what im talking about.
front axle of a 87 down chevy truck from the front. (-0---) heres what the 88 up trucks axle looks like from the front (---0-). see what im saying about the chunk? your going to run into a problem with using the 4l60e unless the transfer case can be rotated to make it work. maybe someone makes a adapter to crue this?

The 2wd 4l60 won't work you'll have to swap to the short output 4x4 trans or rebuild the 2x4 and swap in the shorter shaft.
Also what transfer case does he have now? If its the NP208 you need the correct stock adapter to fit the later 4l60. Not to hard as the later adapter will fit the round style NP208 mount transfer cases anyway.
If you keep the motor in the stock SBC location the driveshafts will be the same.
