Editing How to identify a Ford V8

{{youcanedit}}

==Flathead Ford V8 (136/221/239/255/337)==
This family includes all the Ford V8's produced from 1932 to 1953 (and f.uck you).

===1932-1937===

21 studs hold on the heads of.

32-36,water pumps located at the front of each head, upper radiator hoses attach to water pumps.
37, water pumps moved to the front of the block, upper radiator attach at outlet in center of heads.  1937 engines may run the earlier water pump heads and use "block-off plates" in place of the pumps in the block.

32-36, poured main bearings until October 1935 when an inserted main bearing engine was introduced. Both poured and inserted styles were available through 1936.  Some inserted engines were stamped "LB" but many were not; there is no sure external way to identify them and many "stamped" engines are bogus.  The oil pan must be removed and mains inspected.  37 blocks have insert mains.

== 335 Series Engine Family (Cleveland) (302C/351C/351M/400) ==
Made in Cleveland Engine Plant #2 or Michigan Casting Center.

Made in Ford Australia-Geelong plant 1974 - circa 1984. 302C & 351C only. 

8 cap screws retain rocker cover. 

Timing chain housing is part of block casting. 

Thermostat housing on block.

Fuel pump mounting bolts are vertical. 

Exhaust bolt holes diagonal.

351M/400: Intake is 12.7" wide the 351C is narrower (Differing Deck Heights). 302C/351C manifold approx. 11" wide (280mm).

It is difficult to differentiate 351M from a 400 externally. The most accurate way is to remove the oil pan and look at the crank.

400 Crankshaft ID. http://www.tmeyerinc.com/400crankshaftid.html

351M/400 share the same transmission bolt pattern as the 429/460 (385 series)motors. One exception. The 400 was available with FMX in full size Fords in the early 70's and has the smaller bolt pattern.

All 302C/351C blocks use the smaller 6 bolt transmission pattern, C4 or "Windsor" type etc.. 351C's were available with 4 bolt mains (HO or Boss). 2V heads and 4V heads were used depending on option. Originally 2V meant 2bbl carb. and 4V meant 4bbl carb. However it was soon discovered that the huge 4V ports were not much good for street applications.

'''351C and 351M crankshafts''' are not interchangeable. They have the same stroke but journal diameters are different, 2.75" Vs 3.00". Connecting rods are not interchangeable between "M" & "C" motors, 6.58" Vs 5.78". 

'''Australian Crankshafts''' are Cast and have a raised 302, 351 or 4MA I.D. cast into the crank. Australian 302's have a longer connecting rod @ 6.00" (351C @ 5.78")

'''Heads:''' 
Australia built Clevelands have 2V type heads, 59cc Closed chamber heads on 302C and 74cc open chamber heads on 351C. 

'''Blocks:'''
At some point during Australian production the casting "CF" at the top of the rear of the block, next to the oil pressure sensor outlet was changed to "GF". Also at some point late during production in an attempt to reduce the clevelands tendency to overheat, a "pillow" block was produced to increase water capacity around the cylinders.

A "Nascar" block was produced by Ford Australia (exact year unknown) for the US market. Exact number shipped to the USA is unknown. These "Nascar" blocks were to have thicker cylinder walls and "better grade" cast iron, but due to bad core shift were no better than standard blocks. It is known however that most of these blocks were returned to Australia. These blocks were then used in regular production back in Australia.

Australian blocks have a "cast in" thermostat bypass plate, not stamped steel type. 

'''Intake manifolds and Carburetors:'''
Australian built clevelands used either a Cast Iron 2bbl or 4bbl manifold in 2v size ports. Initially 302C's were only available with the 2bbl (1974-1976) and 351C's had either a 2bbl or 4bbl option.

Rochester carburetors were used on the 2bbls with an aluminum adapter plates. Carter Thermoquads were used on 4bbl spread bore type manifolds with an aluminum EGR plate. Early production 4bbl manifolds had large secondary inlet ports. Later production 4bbl manifolds had the secondary ports reduced in size in an effort to increase mileage and throttle response particularly on 302's with the 4bbl option.

To confuse matters Australian production 351C motors were mixed with US built clevelands (mostly 4bbl Autolite motors) through to about 1976-77. Early Australian production 302C's 1973-1975 (XA-XB Falcon)used US blocks with Aussie heads and crankshaft/conrods. Then it appears that US built "C" blocks bought by Ford Australia were used up to the late 70's in regular production.

== Sixty Degree Engine Family (221/260/289/302/BOSS 302/255/351W) ==

6 cap screws retain rocker covers. 

Thermostat housing on intake manifold. 

Exhaust bolt holes horizontal.

302 BOSS Engines (69/70) have Cleveland (335 Series) style (canted valves) heads and the block can be identified by screw-in freeze plugs.

Timing cover/water pump, put your thumb on the timing cover above the water passage, is it
touching the head? It is a 302, Is it touching the block? it is a 351... (The 351W having a higher deck)

=== Where Made ===
221, 260, 289, and 351W were made in Windsor.  302s were made at Cleveland Engine Plant #1; the last one was shipped the week before Christmas in 2000.  The last four months the plant built ahead for Ford of Australia,who continued to install those engines in new cars for about 2 years.

4.2L/255 CI (1980/1982)

In 1980, an urgent need to meet EPA CAFE standards led to the creation of the 255 cu in (4.2 L) version, essentially a 302 with the cylinder bores downcored to 3.68 in (93.5 mm). Rated power (SAE net) was 115-122 hp (86-91 kW), depending on year and application. Cylinder heads used smaller combustion chambers and smaller valves and the intake ports were ovals whereas the others were rectangular. The only externally visible cue was the use of an open runner intake manifold with a stamped steel lifter valley cover attached to its underside, giving the appearance of previous generation engines, such as the Y-Block and the MEL. It was optional in Fox chassis cars including the Mustang and corporate cousin Mercury Capri, Thunderbird, Fairmont, and standard equipment in the Ford LTD. Poorly received thanks to its dismal performance and mediocre fuel economy, it was dropped after the 1982 model year, and is considered one of the worst modern Ford engines.

== 385 Series (Lima) -- (429/429BOSS/460/370 Truck) ==

7 Retaining cap screws in rocker cover

You will also find some of these engines in industrial applications (towmotors, etc.)

BOSS 429 engine has a semi-hemispherical combustion chamber, also known as a "semi-hemi". Easily identified by large valve covers with spark plugs through the center.

Intake runners are over and under- Center exhaust ports are close together (similar to a SBC)
