The county owned a 69 F950 534 with Marmon Herrington All Wheel Drive for snow plowing. With chains on all 4 wheels, It moved. a house that was on skids weighing over 80 tons. Before they used this truck, various combinations of big GMs and Intl could not move it .
When I was going to high school in the early 60's on occasion I got a ride with a guy that had two ford tractor trailer dump trucks with 534 engines. His worst one needed a valve and a valve job at 250,000 miles. Before this he had three GM trucks and was on verge of bankruptcy from repairs when a Ford dealer took the GM units and put him in one of the Ford's. He never looked back and his drivers were always over 40 yrs. He was getting 3 mpg haulling those heavy loads. On another topic the trucker that picked up the milk from the farm had an IH with a huge 6 cyl I think it was 600 or 700 ci. I saw one years later in a Grove Crane. They were also a very good engine.
What I DO know is that this was a 40kt boat, which was darned fast in 1972 for a 46' motoryacht. A guy who knew the boat said when the captain laid the sticks forward, the beast would make this ungodly sucking sound--no mechanical noises came past the lead lining in the engine room--and the nose of the boat would go way up while the stern squatted. After a second or two, the bow would slap down and it would just take off.
I still have one of the water-cooled intercooler housings, the carburetor plenum (it's the blue thing in the pic above between the turbos and is also water-cooled), and other plumbing if anybody's interested. Here's what the intercooler looks like. It bolts to the manifold where the carb would go. My guess is it would fit any 4-barrel manifold.
I bought a '74 Ford 900 Fire Engine a few years ago with a 534 and 5+2 manual trans from a fire department in Illinois. When I showed up to get it the Chief couldn't get it to go into second or third gear, so I drove it home about 400 miles using 4 low, 4 high and 5 high. You really had to slip the clutch to get it to roll in 4th... The worst problem was, when I was only 20 minutes or so from the repair shop I stopped for gas, and then couldn't get it back into 4th. So I drove the last hour at 20 mph down the highway - good thing it was 1am. Turns out that the gears for second and third were missing some metal - I guess the fire fighters thought they were driving a sports car! When I had the transmission rebuilt it cost almost as much as buying the truck in the first place...
i have a 534SD out of a 1967 C600 and was wondering what one is worth in running condition waith about 60,000 miles on it. i bought the truck for some body parts and have the motor and heard form a few people that it may be worth a pretty penny. but i am unsure and was wondering if anybody knows and if so if anybody needs it. let me know either on here or email me if interested in buying it at firstname.lastname@example.org
