Re: '55 F100 new project, new member
It looks like a basic early to mid 60s pickup engine set up with the modern Autolite 2100 carb that will function the distributors of that time frame, ie centrifugal advance with vacuum load control. This was the latest stuff used on the last of the 292 engines in 1964. That is as good as it gets for a stock 292 from that period. Distributors can be easily overhauled if the OP wants to go back to the OEM type set up for 1963/64. This is much better than what was available in 1955 since the Y-block was new and still in development flux in that time frame. The old Holley Load-O-Matic distributors back then were matched to the carburetor and left a lot to be desired.
The dash instruments were still 6-volt in 1955 so they were likely abandoned when a previous owner went to the later engine. The instruments may still work since the King Seeley stuff was very reliable. The temp sender was already mentioned and the oil pressure sender is also a King Seeley item in 1955. Instrument voltage regulators are available from several sources to drop the 12-volt system voltage to a usable voltage for those OEM indicators. The rest of the electrics such as light bulbs and ignition components were likely already updated to work. The original wiring harness will work fine for 12-volts but a 1955 wiring diagram will be needed to manage any further repairs or replacements. The engine electrics were likely late components to work with the late engine installation. |

Re: '55 F100 new project, new member
So Allen,
What is your current displacement of your rebuilt engine? Do the 312 pistons make it a .030 over 312 at around 318 cubic inches or a 030 over 292 at around 298 cubic inches? Just curious. Al Hook |

here is the math: new bore is 3.829 inches stroke is 3.30 inches new displacement is 304 cubic inches.

Yours is a fairly astute analysis. The original 272 is long gone. The 292 is from some unknown sedan donor. I am putting on a truck oil pan during this rebuild. One of the first thing I found after buying the truck was that the distributor was in bad shape with lots of end play and worn cam lobes. I put in a new one with Pertronix and proper vacuum advance. Including relocating the vacuum advance port to full manifold vacuum. The 2100 Autolite is retained. The motor ran surprisingly well in this configuration, considering the knackered state of the rotating internals. I acquire it with a 12V GM alternator in place and a set of after market gauges attached to the bottom of the dash. The original instruments are in the dash but non-operational (but may be functional). Frankly the wiring is an absolute mess. The previous owner left the original wiring in place and ran new wire in a very haphazard fashion. All of it will be stripped out and replaced with a new harness.

Re: '55 F100 new project, new member
While still getting the rockers sorted, I have done an inventory of new gaskets on-hand and found an important one missing. This motor has the PCV breather mounted at the back of the valley pan, near the distributor. I attach a useful drawing. I have all the parts in the drawing, but the rubber is rock hard and the gasket 6879 and 44719-58 need replacing. I imagine the little straight hose sections are fairly generic and I can get those at NAPA.
Can any of you advise me as to where to find these gaskets? Or, what model and year of car is best to plug into web based parts data bases to hunt for them? Many Thanks, Allen

I was in a hurry for a Baby Bird oil pan drain plug gasket and they found one on the shelf for a recent big Dodge diesel truck that was a perfect fit. Taking them the old example pieces can make a big difference in finding what you need. . Last edited by dmsfrr; 03-22-2023 at 06:45 PM. |

Re: '55 F100 new project, new member
The trip to NAPA was worthwhile. The counter man took my old PCV "teapot" gasket and found that a Ford Distributor Mounting gasket (1955-95) FelPro PN70194 is the correct size for that larger bottom seal against the valley pan. But, it is a thin paper gasket. So, I bought some rubber-fiber gasket sheet and made my own.
Then, digging around in the unused bits of the motor rebuild gasket set, the umbrella-style valve seals looked just the trick to work on that 1/4-20 bolt at the top. Trimmed off the skirt portion and kept just the flat top part. Job done. Have no fear, the valve have seal installed. The machine shop put them in. The ones in my gasket set are extra.

Re: '55 F100 new project, new member
How can I place an add in the swap meet? How can I inquire about something for sale? The Ford Barn seems very restrictive and cumbersome to a new member. How can I find out how thigs are done?

valve adjuster interference torque?
I am having an unexpected challenge with the refurbished rocker arms.
I know these are an interference thread that is meant to be tight enough so as not to move while the motor is operating. But what minimum torque should I be getting from a "good" rocker arm and adjuster? What do you folks deem to be acceptable? I am using an electronic torque wrench to measure the applied torque to move an adjuster. The values I get range from 19 ft-lbs down to 0 (zero). The 0 ones are actually somewhere below 3.9 ft-lbs, which the minimum my wrench will display. If I throw out the "0" rockers, I have 16 rocker/adjuster pairs with at least 5 ft-lbs. Three of these are at 5 ft-lbs, the rest are over 10. Are these good enough? My recourse is to cherry-pick from the old rockers and send a few to Rocker Arms Unlimited for refurb.

Thanks Greg. Yes, the old truck is the project that keeps on giving.

Re: '55 F100 new project, new member
I decided to shift the adjusters over to the two-piece style. I have enough rockers with the milled flat on the top that I readily do this. The two-piece adjusters are available new as a part for the 390-428 FE motor. The ball-end is 3/8".
After installation I set the lash at 0.020". This value comes from Ted Eaton at Y-Blocks Forever. He says that with cast iron heads and rockers the cold 0.020" gap will result in 0.019" on a warm motor.
