It does start F25. but from what I have been told some special order 350's started out as 250s.
Whoever told you that horse dung had absolutely no friggen clue, because there is no such thing!
Compare the VIN on the registration with the VIN on the Warranty Plate to see if they match.
People replaced damaged left doors with used doors. 99% of the time, they did not install the original Warranty Plate on the replaced door.
How can you tell the outward appearance differences between an F250 2WD and an F350 with SRW? The emblems are different, one sez F250, t'other sez F350.
And, emblems can be swapped around. Look for the hidden frame VIN, then post what it is.
If a truck is a domestic special order, it will have a 6 digit DSO code. If not, the DSO code is 2 digits.
The DSO code will be found on the 3rd line of the Warranty Plate.
F250 2WD Series codes (first 3 digits of the VIN): F25 = F250 2WD Pickup / F27 = F250 2WD Cab & Chassis / X25 = F250 2WD Super Cab Pickup / X27 = F250 2WD Super Cab Cab & Chassis.
As I recall, the vacuum diagram is on the left valve cover...is the cover original to the truck? Is the engine original to the truck?
It's also possible that the wrong diagram was installed...how about posting a pic of the puppy.
If you want the facts, contact martiauto.com. Marti has ALL the original records for 1967/79 FoMoCo vehicles, Ford has none of it any longer.
In the late 1980's, Ford was planning to THROW AWAY these records. Kevin Marti, a 'Mustang nut' in Phoenix AZ found out about Ford's plan and got ALL of it.
Couldn't he also check the axle ID tag and see if it corresponds with the axle code on the door plate? Or do the same with the trans code? If the door was replaced and the tag not swapped, he might find a hiccup in the numbers somewhere. Even the casting numbers on the block?
Ok alvin fire department owned truck till 1984. Then the retiring fire chief purchased from city and after he died his son owned until the guy I bought it from bought it. No wrecks.

If an A/T, Ford used the SAME trans code for all A/T's used in 1965/78 F100/350's: G
One had to know which trans was used with what engine.
The T-18 4 speed trans code is the same 1965/79: F
The NP435 trans code is the same 1966/79: A
The 3 on the tree M/T code is the same 1966/79: C
Casting numbers on engine blocks are worthless for ID'ing the size of the engine (except 1979 460's w/a D9TE-6015-AB number) or what it came from.
Casting numbers are foundry marks, cannot be cross referenced to Ford part numbers.
The Ford ID tags on Dana axles are under one a the bolts that retain the inspection cover to the housing. Today, many are MIA.
The Warranty Plate AXLE codes could be the same 1973/79, but don't count on it, cuz Ford changed the codes more often than women change their minds!
Ditto COLOR codes.
Doesn't really matter if the Warranty Plate is original to the truck...or not, since the VIN on the registration begins with F25.
But, what the OP hasn't done is...compare the VIN on the registration with the VIN on the Warranty Plate and the hidden frame VIN to see if they all match.
