3/4 ton swap

Ok .. here is the situation ..

A buddy and I are going to strip down his '87 YJ of all its driving components and swap in a 3/4ton chev into it. We are looking to make this as quick and simple as possible, but neither of us have done this kind of swap before.

We have both swapped like-for-like engines, parts, drive-train and such, and even some minor upgrades .. so are just looking for something that can point us in the right direction.

What we have is:
  • Chev 350
  • TH350 transmission
  • NP203 T-case
  • Full-width axles
  • Full 3/4ton truck to steal any parts from that is required.
  • 1987 Jeep with 3" body lift and 4" spring lift

What we are looking for are any special motor mounts to put the engine in its place (heard we can use the stock Chev motor mounts, cut them off the frame and weld them onto the Jeep), special T-case skidplate required (where to find, or instructions to make), best way to mount full-width axles (don't care to cut them to size), best way to do the axles as SOA?

When we are finished, it will have 35" Baja Claws mounted on the new rims.

Any tricks, tips, hints for us to follow .. is there a book that we can purchase with that kind of information in it?

Thanks!

Quick update on our swap:

Engine/Tranny/T-case all one unit is mounted in between the frame rails.

Camero auto-shifter mounted, ready to be cable'd into place.

Axles strapped to the spring packs in SOA style.

Brake lines replaced and bled.

Radiator from a 1950's Fargo mounted with electric fan and mechanical fan.

TransCooler mounted in front of radiator.

RearDrive shaft ordered and will be ready for pickup / install on Monday (today is Sunday)

Steering, front drive shaft, dual battery setup and some electrical wiring still to be completed.

Jeep to be ready for next Saturday's Show and Shine if everything goes according to plan.

3" body lift, 4" suspension, SOA running on 35 x 14 Baja Claws .. its a tall beast!

All that we did was plug away .. we don't have a working speedo or tach yet .. we have an aftermarket oil gauge installed .. but the rest all seem to work fine.

As far as websites go, we didn't use any .. just grabbed the Haynes manuals for the Jeep and for the Blazer and one dedicated to engine tech (Chevy V8 engine rebuilders guide by Haynes) to make it all work well.

Laters!
