4.0 Swap, a continuing thread.

[Nunner]

**** When I started this thread it was going to be a 4.0 head swap and Chevy TBI, then changed to a 4.0L swap and finally became a 4.6L Golen Stroker swap so that is why the thread switches around a few times.******


After much debating I decided to do a 4.0 swap on the YJ, when I began the teardown it was going to be a 4.0 head swap and Chevy TBI conversion but I just decided to go all the way. I'll probably be pulling the motor this weekend but here are a few pictures from when I was planning on doing the other swaps:

This was for the head swap:

First off with the valve cover:


Now working on a couple of the head bolts:


I'm sure this wasnt impairing my cooling system at all:


Intake and exhaust manifolds off:


The ever important parts table:


And the head off:

Wiring for the Chevy TBI and the TBI:


Working on getting everything separated:



I hate wires, but everything ready to be torn down:

[Nunner]

[RescueJP]

UPDATE: I decided against both the head swap/EFI and a standard 4.0 swap so here's the new build: 4.6 Golen Stroker and NV-3550 Swap:
