Ken, The GEP NA heads are the square stamped pre-cup and the intake manifold bolts are 90° to the intake port surface. The GEP turbo heads are the same casting number but have the diamond pre-cup and the intake bolts are 60° to the intake port surface. A CUCV NA intake can be modified to fit...

I started writing before you posted the battery question, got busy with my students and then finished after you had posted. Cummins starters and alternators are available in 12 or 24 volts. I have never searched, but I am sure there are ways to mount a second alternator to a Cummins BT engine...

4L80E to transfer case. The CUCV trucks all had TH400 transmissions with a 32 spline output shaft. All of the trucks had either a NP208 or NP205 married transfer case. If you find a 4 wheel drive 4L80E with the pedestal/transmission mount bolted to the back of it. Then any CUCV 208 or 205...

I went through this thought process a year and a half ago when I started the Cowdog truck build. GEP 6500, 4BT or 6BT? 4BT was just too much money for the same basic performance as a 6.5 with a turbo and actually less road speed. But, in theory longer engine life. 6BT would be great...

Nothing I own MV wise is 100% stock. I have no problem making something different to fit my specific needs. I have 5 6.x powered vehicles on the road pretty much every day. Here are my observations: The 3 24 volt starter trucks all start no matter the conditions or how long since they last...

I added the long torque rod to the Cowdog truck. None of my CUCV trucks have it, but the 6.2, TH400, NP208 originally Cowdog did. I figured it couldn't hurt. I had to lengthen it 1.5 inches because the 4L80e is that much longer.

Oh, that. I went and looked at some backing plates just to check. Yep, they are there but not supposed to be loose. Good call n what they are.

That machined elbow looked really impressive in person the other day. Did the starter work?

Only the Delco 195° thermostat showed up by this afternoon. I siphoned out 1.5 gallons of coolant and pulled the 190° Murray unit. Though only used for 354 miles. It had a crack on top. I tested the new one on the stove. It opened at 193°. A quick install and ready to test it out. Once fired...

I think I've done 12 hub flips and many tear downs too. I really don't recall seeing that spacer. Interesting.

Yes, that bracket can be swapped out. There is a C clip that has to be removed and a 1-7/8" open end wrench to pull the nut off.

A spot weld drill bit will be a huge help getting the radio mount rack on the dash off. A hole saw set will come in handy for the holes in the valence and firewall. 5 total I seem to remember. Be very, very, very careful with the vent plate that goes on the dash pad. Mine broke in several...

Stock was 31 x 10.50. So, if that is the size you get the speedometer should be right on. Or, at least as right on as they were back then. Within 3-4 mph.

I have several thousand miles of M35 driving with a civilian chase vehicle. When I am in the M35 I like the civilian vehicle in front. We always use two way radios. Unless you have an aviation type headset in the M35, you can't hear what the other person is saying. However, they can hear...

Yes, the smaller tires will improve your fuel economy. If you drop your speed down as well. As pointed out above, thinner street tread tires will really help as well. You didn't state if you need to run a higher speed for your drive or what kind of drive it is. All city and or open road...

Dakota Digital states many times in the manual that the temperature sender is accurate only between 100° and 300°. As mentioned a few post up. They publish the Ohm readings for the sender at 100, 200 and 300 degrees. I was told on the phone that 72° should be 850 Ohms. The Ohms go down as...

I agree with you. I have 2 M101A2 trailers and 2 M105A3 trailers. The 105's haven't left my property in a few years. The 101's get used a lot. I camped in mine at the Texas Rally a few months ago. However, at times they are a bit bigger than needed. I had been pestering Kwai for years and...

I just had a student test a redux here in my class. It works. But, I am not sure if it is 12 or 24 volt. No markings. I have another spare redux known 24 v at home as a spare in RED. I got educated on the phone today at lunch. Called Heath about their super duper fan clutch. It only fits...

The flexplate teeth are straight cut.

I have a 12 volt redux on the Cowdog. 12 volt direct drive on the Blue Bomber. 24 volt direct on the M1009 and M715. RED has a 24 volt redux. I have 4 or 5 spare 24 volt direct drive units and I think a single spare 24 volt redux. I will be in B/Cs Thursday afternoon and then all day next...
