What is the difference between a single front mount 223 and a dual front mount 223? Is it a year issue? Why are the blocks different?

 

Different mounts were used for different sized trucks. The 1957/60 F100/250 used one type, the F350 and larger trucks used a different two mount system. It prolly had to do with the weight the trucks had to carry, and the stress put on the engines because of it. The same 223 engine block is shown for 1957/60 223's. The 262 engine was introduced in 1961. It looks similar to a 223, but has beefier internals. Both the 223 and 262 were made thru 1964.

 

The single plate mount block has a cast timming cover and the dual mount block has a stamped tin cover. What is the difference in oil sump pick up location? i.e front/rear
The 250's have dual mounts. But still shouldn't the blocks be the same? Why is the block it self different?

 

It's not, at least according to the parts book..are you sure you aren't looking at a 262?

223~Same: Short block 1957/60; Oil pan, pump and pickup tube 1958/60. 1957 uses a different oil pan, pump and tube. Parts catalog makes no reference to 4X4 using any different.

 

223 (3.7L):
1954-1964(7)
bore 3.625 X stroke 3.6
Chain driven cam, distributor in front right, ’54-60 used 7/16” Head Bolts, ’61-4 used ½” head bolts, ’54 – 59 2 nuts holding down valve cover, ’60 – 64(5) 8 bolts holding down valve cover, ’63-4 Police Interceptor & Special Taxicab engines used a gear driven cam.
Found in light trucks & cars, tractors & industrial applications, Found in Ford model 6000 gas tractors
Found in DIVCO trucks as the "F" series motor to '65(?)
’55 block & intake painted yellow, valve cover silver
'63-4 painted same as 170 ci I6
Door codes; cars- '54-'59: A, '60-'64: V
trucks- -'64: J
Extra info - marketed as the "Mileage Maker Six"
262 (4.3L):
1961-1964(7)
bore 3.718 X stroke 4.03
Gear driven cam, distributor in front right of block (?),’61 – 64(5) 8 bolts holding down valve cover, early/big truck models had a fuel pump driven by an eccentric on the timing gear, later models (’64) had the fuel pump driven by an eccentric on the cam, exhaust manifold didn’t have a heat riser as the carb used a water heated spacer.
Truck only motor ('61-4 C550 & C600 tilt cab trucks, F600 trucks, B600 busses, ’64 light trucks), possible industrial applications
Found in DIVCO trucks as the "G" series motor to '65(?)
Door code- ‘61-'64: B
Extra info (thanks to the inliners site):
- The Hollander exchange manual says the 262 was made from 1961 to 1964.It will replace a 215 or 223 by switching some parts depending what the motor is going into. 223 heads can be used on the 262,but different years use different temp. sending units. Also early 223 heads will have to have the head bolt holes in the head drilled out so the 1/2-inch head bolts can be used. Intakes interchange, as will exhaust manifolds, but check the header pipe size and location where it fits on the manifold. Rocker arms of all types interchange. Three types of connecting rods were used.1961 to 1963 had heavy-duty cranks (steel)? And 1964 had both light duty (cast?) cranks and heavy duty cranks same as 1961 to 1963.Oil pans should interchange, but may have a larger capacity or a different sump location. I would pickup a Ford master parts catalog for more information.
The Jan 96 12 Port news has a brief article on the 3 heavy truck engines: Chevy 261, Ford 262, and Mopar 265. It mentions that the Ford has an extra massive cast rib on the left side above the oil pan; 3.72 bore and 4.03 stroke; and full low oil filtration.
Combination Possiblities:
215 + 262 crank - 241 (3.56 X 4.03)
223 + 262 crank - 250 (3.625 X 4.03)

This series of motors were last produced in 1964, though info from truck manuals suggests that they were produced till '67 for truck/industrial applications. These motors differ from most ford I6s in that the intake & exhaust are on the left (driver's) side, much like the GM I6. Some parts will interchange with the Y-blocks. A 240/300 distributor can be used on the '64 and later blocks with the 5/16" oil pump shaft. Earlier motors can be upgraded with this equipment, but may need machining of the distributor hole & the oil pump will need to be changed to the later style.

 

Yes, but why is the block different?? The mount castings are not the same. Does the year have anything to do with it?

 

How do I decode the block?

 

Does the 262 use 2 bolts or 8 for the valve cover?

 

The engine I think was in a 55' truck. I don't know the model.

 

I'm looking through the book to find stuff that is different you can visualize between the 262 and a 223. Both use 8 valve cover bolts 1961/64. The 262 valve cover is different, but the book doesn't say why. Mebbe its longer because the valve cover gaskets are different between the 223/262. The timing covers both have 10 bolts holding them on, but 4 of the 262's are longer. The dampers are different, but no ref as to why is listed.


How about this? ~ Does the engine have a timing pointer? The 223's didn't have one, the 262's did.

 

It only has 2 bolts for the valve cover. I don't think it is a 262. Everything looks like my 223, but it has a cast timming cover, were mine has a stamped one. It just does not have the castings for the dual front mounts. It does on the driver's side but the pass. side does not. How do you tell if it is a 215, dist. location?
