This motor is fast, with no load.
They seem to be pretty fast with a load too.
Great progress!

i had to divert my attention to my M37 today. I have put this off long enough. The old girl needs a fuel pump, possibly the first one ever. I have owned it since 1987, and I have never replaced one. So, I got one from my friend John B. at Midwest Military, and spent a few hours getting the pump installed, primed, and running this morning. Now I can move on with Woodstock.

Getting the left side tuned up and primed is the highest priority today. Some bodywork, some filler, and it is good enough for now. This might be the last 2K primer, or paint for that matter, for this round. Yes, it will be temporarily multi-color, but I'd rather be camping and drinking beer this summer than worrying about how it looks.

So, I don't have a lot to show, but this opens up a lot of assembly. Left rocker, roll cage final bolting, seats, and more. Testing at Twin Peaks next weekend.

You should go.I like the Jamboree sticker collection.
I said I would drive it by this weekend, and somehow, with all the other outside forces working against me, it is drivable. I worked this morning on some tuning issues, and found out that Holley software doesn't recognize Apple products, i.e., my laptop. So, I decided that one of the biggest reasons I bought the Terminator X, is because it comes with a hand held touch screen, and I can use that for the adjustments I want to make. So, a little youtube university, and I made the adjustments necessary, and deemed it ready to try a drive. To back up, there were about 25 items on my list to make it drivable, and I got through most of that first. Small stuff, like seat belts, tie up wiring, body mounts, stuff like that. Then a drive around the block, and I didn't have to walk home, so that was good. Then I got adventurous, and headed into a trail that is a few blocks from my house. It's running good, shifts, 4wd works, overdrive works, no bad noises. I stretched it on a rock to see how it looks.

These spring-overs have a lot of flex, and I think this jeep will come down another 3" affter some driving and wheeling with a load of beer and cast iron cookware. On flat ground, it's sitting at 31" under the rocker. Nick's is 28" with the same springs, so we'll see.

I don't think the rear is flexing as much, the frame is 7" wider, so the pivot points are further out. And there is no weight in it. Once the spare tire rack and gear is in it, I think it will stuff more. This gives me an idea of what my bump stops need to be, but I really need to take it to a real trail to flex it. Tomorrow, I hope.

I worked all day and only took 2 photos. One is good, one is bad. First, I need to d rive it, so I went for a 30 mile run to the top of Luther pass and back. The good-it runs great at 55-60, 3000rpm in direct, 2000 in OD. It will pull the pass in OD no problem. Reached the top of the pass and it just touched 180 degrees, so cooling is still good.

The bad-it started making bad gear noises on the way back. When I got home it wouldn't stay in second gear. I pulled the top to look at any shifter (wishful) issues, compared it to 2 other SM420's I have. I see no issue, until I noticed the mainshaft will move about 50 thou forward and back. Not good, and I think that would explain the jumping out of gear issue. I next pulled the OD, it was tight. Pulled the transfer case. I am thinking something with the adapter/spud shaft.

Bingo. I think that may be exactly what is going on. I will get a dial indicator in there tomorrow after work to see what I need.When I replaced my t-90 mainshaft the A-A mainshaft had an issue and i had to make a special washer for the D18 bull gear because the overdrive would pull tight to the internal nut but the bull gear splines allowed it to float under the nut.
