Major swap in my future
This weekend I am taking delivery of a 1988 Chevrolet Suburban with 95K miles. It’s a 4X4, 3/4ton (disk/drum), 4 speed manual, big block.
The current DRIVE TRAIN in my 72 SWB K10 is a 350, TH350, 203 transfer, and six lug bolt pattern on the axels. Going to swap the motor, tranmission, rears, transfer case. My questions for the board are: •Will the rears fit without moving the springs? •Will the 454 fit in a 4X4 engine compartment? Read the BB motor needs to be moved but can’t find the thread •Will the shifter come through the floor at a useable position? •Has anyone had a drive shaft balanced? Does it really make a difference? Any and all lessons learned would be appricated. Dale_Brown Last edited by Dale_Brown; 02-07-2013 at 05:15 PM. Reason: S |

Re: Major swap in my future
to answer your questions
if you are just going to put the rear axle in and leave the 1/2 ton springs yes it will work if you are running a HEI dizz move the crossmember forward 1-1 1/2" to allow clearance I am not sure on the transfer case shifter, what transfer case? I think that 88 has the shifter on the drivers side?? again not sure. YES balancing a drive shaft is DEFINATELY worth the money. Coop

Re: Major swap in my future
Stock transfer case for a 72 would be the NP205, not the NP203. Not sure if you actualy have the NP203 or not, just making an observation...

Re: Major swap in my future
Is the donor Suburban really a Big block? Big blocks did not appear in 4x4 Suburban’s until the next body style in 1992. Maybe the PO swapped it in?
