We Have A Fire Truck With A Rebuilt 534. The Problem Is We Can't Find Any Info To Set The Timing On This Engine. Can Anyone Help. we need this unit online asap.
I'm going to the library in a couple days to look up some 292 info. I'll jot down the 534 tune up specs if that would help.

My brother use to drive 534 powered Ford trucks, F1000 models with dump trailers. He said that they could haul heavier loads than any other gas powered trucks and even outpowered most diesels. 300-400 thousand miles on them before any major work was not unusual. He said that another truck company bought a GMC 702 cu in V12 , and it was an equal to the 534 in power but it's gas mileage was much worse.

Reason: spelling
I don't know that I would say the 534 was the equal of the 702 power-wise. The GMC 702 'Twin Six' was something of a legend in its day. I knew a guy that was a mechanic for a trucking company that ran them back when. He said they would run away from everything, gas or diesel, by a wide margin. No doubt the 534 was a powerhouse, but they never made close to the 300 h.p./600 ft. lbs. of torque the 702 did. Those were big numbers in the early 60's. Most the Minuteman mobile missile launchers were powered by 702's, right up into the 90's.
Interesting comments about the GMC 702's. My brother said that they were powerful, but they couldn't run away from everything, and he could beat them on many hills carrying the same load. Maybe his Ford f1000 was geared more effectively. The v12's were rated at 275 horsepower and 585 ft lbs of torque. The 534 in its initial offering had 277 horsepower and 495 ft lbs of torque. Also, gas mileage was much better with the 534.
The old gal needs some paint but shes special to me because about 25 years ago a friend of mines father restored the truck and i remember it like it was yesterday. The truck has been sitting all of these years and i consider myself a rescuer of sorts. Oh yeah, the truck is a 63 and was all original until i put a Edelbrock carburator on it because the original Holley was flooding the plugs.
I checked your trucks out and i do like. The same man i got my truck from has a N series he bought new in mid 60's. It has a 391 and was twin screw and two stick trans. It now is single axle and 5 speed. He used to pull a log trailer with it and now in his retirement uses it as a flatbed to haul hay. He also has a Lousiville cab gas burner that he also uses as a flatbed to haul hay. I sawed up a white oak tree for him and he used the lumber to build a wood bed for the truck. He is in his 70's and can build or rebuild anything. A truly gifted person.
i have a 70 f-900 dump with a 534 in bought it for 1000 buck did some carb and distributor work to it runs like a charm need to do a little external work and will be on my way does anyone know where to find some motor parts for the 534
Well, I'm not really "the owner" since the 1969 F850 Super Duty actually belongs to the Superior Fire Department, but I get to work on it and they supply the gas to drive it. It is retired Fire Engine #4. Purchased new in 1970.
I runs really bad, no brakes, leaks fuel from the accelerator pump diaphram all over the manifold. The dizzy has been rewired 15426378 so it pops through the carb and the exhaust alot and hits on what ... about 6 or 4? I used a temp gun to see which were firing, not many.
The brakes were out juice, but even after filling and bleeding it would like some more vacuum to do a proper stop.
I've been looking online for some correct information on the engine numbering and firing order for the 534. The firing order is cast into the intake under the carb so that's easy, and it is not the same as all other Ford engines that I have known. Also the left bank is further forward which would tend to make one believe that the cylinder arrangement is unique also. When someone tells you to look at the numbering sequence cast into the intake, they are not talking about a 534. It just ain't there, and there are no "runners" like on an FE. The runners are in the head, not the manifold.
I read a lot of tune up specs in this forum, but nowhere is there any mention of valve lash. You have got to set'm to do the job right. I found them all over .040 so I just faked it and set them at .010 and .015. I'd like to find the actual specs though. Is there a link to an online reference?
The points were smoked, so I filed'm and set them like it was mine. I'll check dwell after I get it to quit shootin ducks. This bad boy needs some work.
Does anybody out there have a Super Duty Shop Manual where we can read the gospel from the good book?
