Taking the plunge and posting this mod/build if you call it that. A get er done with basic tools and beergineering swapping from a Dauntless carb V6, T18 6.xx 4spd, 3.15 D18, 4.56 narrowed Waggy D44s to 2000 Chev 4.3, 4L60E, NP241, same 4.56. Sorry, not going to be a topnotch build like so many of you do, rather a low budget, factory parts for reliability, using basic tools and hoping to have completed by June and yep I barely started. Will be asking for help and feedback, so share away. Going for short stretch and retain body proportions. Bought it 21 years ago with a fiberglass body and the Dauntless, added the rest including 35’s, rear spool and front arb, 3,500 #. Gets used 50%+ offroad in Colorado, rocks, snow wheeling in Spring. Goal is to have it be more capable and cannot wait to shift as needed under load. Is fully caged to frame including front bars to radiator hoop. Did same swap to a 72 Commando a few years back. I going to miss the current drivetrain as it works well, but I tell myself go auto so I can shift full throttle and more.
Some details
Few things I could use help with to start.
Am I going to kick myself with an auto and miss the current set up that I dreamed about having 35 years?
Some details
- Thinning a S10 harness and using the underhood fuse box for all electrical – 75% complete.
- PCM being tuned by Jims Performance - ready to send with some experienced advice from this group.
- Using original frame, cutting it behind front leaf rear hanger adding all the length in mid-section, widening front section a bit and the rear section a bit more. Weekend away from completing snow plow mount on Commando and then off the body comes. Willys is my current plow and living at 10,000 feet I need a plow.
- Done the math and have a plan for a 15 to 21 inch rear d shaft depending on rad fan – mech or electric.
- JB conversions shorty sye – need shift fork pads to complete install.
- Clocking the NP241 with GLO ring – need to purchase.

- Need more gearing?
- Cooling fan – not ever run electric. Taurus, Lincoln, is there a better one?
- Do these programming mods Jim Perf recommended sound good
- Increase line pressure from 90 to 120 ( I think 120 is what he said)
- Speed/firm up all shifts 1 to 2, 2 to 3, 3 to 4?
- Raise rev limit by 200rpm
- Turn on electric fan control
- Deleting post cat O2, vats, evap, keeping egr if exhaust manifold and steer shaft will clear.
