f100
i would like to ask where I will find the engine number on the motor in my 66 f 100. I want to see if it is the original motor and if not, what it came out of.
I am sure by later this evening you guys will have helped me as usual.
Once I locate the number I will once again ask you if it is the one that came in my truck.

Your VIN will tell you what the truck came with. Odds are the aluminum tags the engine had from the factory is long gone.
There is no such thing as matching numbers.
You need to measure the bore and stroke.

There is no engine number. The last year trucks were registered by their specific engine numbers was 1947! VIN's introduced in 1948, register the entire vehicle.
The block will have a casting number on it. Casting numbers are foundry marks, cannot be cross referenced to Ford part numbers. Are WORTHLESS for ID'ing the engine size or what it came from.
There will be a date code on the block, but all that relates to is the day the block was cast. Blocks after being cast, are then placed outside to "season."
When the block is assembled, it could be...as long as a year from the day it was cast...before the complete engine is installed in a vehicle.

sorry it is the 6 banger translates to the 3.9 these days. we already did the door tag # just wanted to see if they changed the intake and the carb and valve cover or they changed the whole motor. like I said it has an egr valve and a hole in the manifold for the valve so I figure it all has been changed. I knew Numbers would have the info

SP, Keep in mind the numbers on the truck tell you how it left the factory door, not what might be in there today. In 40 years the engine could have been changed several times.
Did you mean 4.9?

these days.

Lke I said it has an egr valve and a hole in the manifold for the valve so I figure it all has been changed.

so I figure it all has been changed.EGR valves introduced in 1973 for all FoMoCo vehicles. 240 cancelled at the end of the 1974 model run.
The EGR valve bolts the EGR/Carb spacer plate. The hole in the manifold is for the EGR tube, t'other end of it threads into the EGR/Carb spacer plate.
First year for this tube: 1977.
240/300 share the same block (casting number will be the same), the bore is the same (4.00"), the stroke is different.
Measure the stroke to verify engine size: 240 = 3.18" / 300 = 3.98"
Look for the date code on the block. My guess is the engine's been swapped, it's probably a 300 from a 1977 or later F100/350 or Econoline.

Numbers,
Where would I find the date code on the block looking from the radiator. if it is either the 77 or the 66 that should have come with it. I am sure when I find it I will have to ask you to decipher the code too.

I have been on the internet looking at 77 300 cid motors that numbers suspects is in my 66 f 100. I have seen a couple pictures and they look exactly like the motor in my f 100, down to the air breather.
On the left side of the block I found d5te(then some numbers I could not read, seemed to be covered with something that gunk and a wire wheel would not take off.) then at the end appeared to be an AA also found a ford symbol and large number 22 on both sides of the block. I have no Idea what this means. I guess the important info is gone.
thanks numbers

Engine you have is a 1975 or newer truck engine. Number for 66 is on passenger side right below coolant drain plug.

yeah I am suspecting it is a 77 like numbers said. these numbers are below the manifold kinda motor mount height. plus it does have some pollution stuff on it egr valve. all these numbers are on the passenger side as I said it has 22 in bigger numbers on both sides.
I am glad I do not care if it is original motor, guy I bought it from said it was...

just did a google search and d stands for the 70's the 5 stands for the 5th year of the 70's
numbers said the blocks sat and cured for a year so he was not far off on his 77 call of the engine. He is one hell of a smart guy who has helped me out many times with my stupid questions..

Depending on demand, it could be a year from the day the block was first cast before the completed engine was installed in a vehicle.
I do not know how many years the D5TE-6015-AA block casting number was used, but the 300 I-6 has to be from at least a 1977, because the EGR tube wasn't used prior years.
EOTZ-9D477-B (replaced D7TZ-9D477-B & D8TZ-9D477-A) .. EGR Tube ~ From EGR/carb spacer plate to exhaust manifold.
1977/83 F100/350 & Econoline / 1980/83 Bronco.
