I own a 1954 F600 Marmon Herrington. Bought it last month. I also own 2 1956 F100. 1 is original. Other is modified. All of them are not road ready yet.

Need help on the F600. Just bought a 1990 D350 with a decent 12 valve Cummins. My F600 is manual transmission. The 12v is automatic. I want to keep the F600 MH parts on the truck. Can I use the F600 transmission on the Cummins?

I want to keep it as close to original as possible.

I suggest that you post this in the proper forum. This is the NEW MEMBER INTRODUCTION forum. I think you need to go here: https://www.ford-trucks.com/forums/forum41/

I notified a moderator so maybe he can move this to that forum.

 

Moved to the 1948 - 1956 F1, F100 & Larger F-Series Trucks forum.

Welcome to FTE!!!

 

Welcome to FTE the best Ford truck forum on the World wide Web!

We have some MH experts here that will be able to help you. Good job with the pics. Thanks

 

Welcome. Your question is similar to one from another new member in this other current thread. It’s a question you might direct to Chuck Mantiglia of Chuck’s Trucks. Stu

I say find a good Y block. Put it back like it suppose to be. What you want to do I think
you will be sorry because of the Marmon low axle ratios. These trucks were not for
highway speeds they were for off road. Diesels operate in a lower RPM range than a
gas job. With a diesel it will be maxed out at 40 mph or there abouts. There are no
high speed ring & pinions I know of for these Chucks truck will know. There is a way
out either a Yblock or a 302 with automatic over drive, or a 5 speed overdrive tranny.
Even a light duty OD tranny don't forget these have Underdrive it will still pull stumps.

 

I own a 1954 F600 MarmonHerrington. Bought it last month. I also own 2 1956 F100. 1 is original. Other is modified. All of them are not road ready yet.

Need help on the F600. Just bought a 1990 D350 with a decent 12 valve Cummins. My F600 is manual transmission. The 12v is automatic. I plan on swapping the motor. Currently there is a 1959 312 Thunderbird motor switch is not stock. I




want to keep the F600 MH parts on the truck. Can I use the F600 transmission on the Cummins?

I want to keep it as close to original as possible.

 

Then rebuild the 312. ( I highly doubt it is a 312) it is probably a 272 or 292. I’d like to know where all the t- birds are without engines are?
you pit the Cummins in there and you’ll find out that the transfer case with straight cut gears is the weakest link
I vote for keeping the y block even if it’s a 312. It is period correct

 

In terms of money value, do you think the MH is worth keeping original? I see parts sell for a lot of money. I do not see any of these trucks for sale. Maybe 2 in the last year from my searches. I do not want to lessen the value but, overall, my goal is to have a resto mod version of this truck with a Cummins 12v and gears that allow me to go 75mph without issue across the country.

I plan to splice 2 cabs for an old school looking mega cab. I love the fact that this truck is a beast as it. But, I do not want to lug around at 40 mph and pull stumps. I want to drive it every day and represent the new old school 15,000 miles a year. i want this to replace my 2014 Ram 2500 crew cab 6.7

So, overall. If I restored this to original with a 54 Y block and kept the gears original and made it perfect and original would it be worth 80k? Or if I restomod it the way I plan would it be worth more?

I will not sell, but, if I need a heart transplant I want to know that my old believed F600 will save my life.

Give me your opinion, please. I will greatly appreciate any feedback.

 

Welcome to the forum. Marmon Herrington converted trucks are relatively rare, but that doesn't always equate to high value. The smaller half and one ton trucks are considerably more valuable because they are in higher demand. They're more feasible to use and drive, therefore more popular. The ton and a half and larger trucks, F500 and larger, have never commanded the same money as their little brothers, be they stock or modified, and probably never will. No matter what you do to it I can't ever see one commanding 80K plus. Ever. People collect and restore MH trucks for their uniqueness and history. MH people, from what I've seen here anyway, are particular to stock restorations, the more accurate, the better. They will typically invest far more than they ever would be worth. It's the love of the hobby that drives most of us here, not the investment value, similar to a fisherman that buys an 80K boat, thousands of dollars worth of tackle and gear, just to catch a fish they can go to the store and buy for ten bucks. I also don't believe the parts involved were ever designed to stand up to the kind of torque that a Cummins Diesel would subject them to. They won't be worth much at all if they've been grenaded.

I don't typically recommend this, but if your dream is to have a daily driver crew cab, 4x4 diesel 54 Ford pickup, you'd probably be much farther ahead to attempt a body/frame swap and build out the Dodge chassis than to try to adapt the Cummins to the MH.

My 2c, since you asked.

 

Thanks for the detailed reply. Originally, when I bought the truck, I assumed it was a bit more heavy duty. Sight unseen, I flew to Oregon to buy it. Once I saw just how massive it was, I thought, the parts can't be installed on my original 1956 F100 project. So, I then turned to the idea I laid out above.

 

New question. Can I take all the Marmon Herrington 4x4 parts and put them on my F100, since I own an original 1956 F100 with a stock v8 and 3 on the tree.

FYI, I love these trucks and would not sell, but, I am an investment manager by profession so it is always part of my decision process.

I can't find an original MH from 1956 so, this is why I wanted to convert initially.

 

Interesting collection for sure. I'm by no means any expert on this whole thing. For the MH they don't seem to have much value at all. Even restored they don't. Very few people know about them. For your plans, I would do what you want but know that these trucks with few exceptions are not good investments. Build them for the love or challenge of doing it. You don't know what will be popular down the road. Right now F100 trucks are popular as well as some older C10 trucks. In five years it could be something else. I remember a time when Dusters were all the rage. Now they are worth very little except to the right person. My two cents.

 

This is my 56 f600 Marmon Herrington that I restored back in 2000. I have since sold the truck
