In 1968, the engine was reduced to 195 horsepower. ===289 HiPo=== *Available from 1964 to 1967 *Higher nodularity content in block with larger two-bolt main caps *Counter weight balanced crankshaft *3/8" rod bolts *Screw in rocker studs w/mechanical lifter camshaft *Dual point distributor *Ford 480 cfm four-barrel carburetor atop a cast iron intake manifold *271 horsepower at 6,000 RPM w/312 ft/lb of torque ===302 cubic inch=== *Produced in 1968 *Cast iron crankshaft *forged steel rods *cast aluminum pistons *hydraulic camshaft *available with 2 or 4 barrel carburetor *horsepower varied from 210 to 230 depending on carburetor *Standard 302 was equipped with 2 barrel from 1969 to 1983 ===302 Tunnel Port=== *Did not see production for consumer market *Commonly referred to as the 302 TP for Tunnel Port *Push rods were fitted inside a sleeve *Intake ports were over sized *Intake/exhaust valves were 2.12" x 1.54" *Two versions available, one with conventional [[rocker arm]s for the Trans Am race series and the other using Nascar shaft mounted rockers *Engines were built by Ford foundry and not by the racing circuit ===302 Boss=== *Top performer of the 90 degree family *Production from 1969 to 1970 *Available in Mustang 302 Sportsroof and Mercury Cougar Eliminator only *Four bolt mains *Screw in frost plugs *Canted valves, 2.23" x 1.71" *Cylinder heads from Ford's 335 Series family *Threaded rocker arm studs *Push rod guide plates *Stamped steel sled-fulcrum rockers *Mechanical lifter camshaft *dual plane, single four barrel aluminum intake *Holley 780 cfm carburetor ===351 Windsor=== A basic Windsor engine design but with a higher deck height than the 302. Not to be confused with the 351 Cleveland. There are no easily interchangeable parts, although a [http://www.darkhorseracing.net/clevor_head_mod.htm "Clevor"] hybrid can be built; [http://www.edelbrock.com/automotive_new/mc/cylheads/ford/cle_perf_rpm1.shtml Edelbrock] sells heads for building a Clevor as well. There is some discussion about early 351W engines being stronger due to higher nickel content. This writer has researched that and so far information found including a FoMoCo statement, it has turned out to be a myth though have still sought the earlier, '71-'73 engines, just in case it's true. The bore spacing and bore diameter between the 351 and the 302/5.0L remains the same at 4.38" and 4.00" respectively. A safe overbore is 0.030", but some blocks will allow more, but before boring beyond 0.030" the block should be sonic tested for thickness. There are two 351W deck heights, 1969-1970 produced engines are 9.480" with the 1971 through end of production in 1995 at 9.503". The crank is significantly different with the mains being 3.00" vs. the smaller Windsor engines being 2.25". The firing order is also different 1-3-7-2-6-5-4-8 (the same as a 5.0L HO) rather than the 1-5-4-2-6-3-7-8. See '''[[Ford firing orders]]'''. The significant interchangeable parts with other small blocks from the Windsor family are the heads. While the heads are in general interchangeable, there are differences in the bolt sizes: 1/2" for the 351 vs. 7/16" for the rest. To use a 302 head on a 351, special intake gaskets are needed. Camshafts will interchange but the firing order will require that the distributor cap be wired based on the firing order that the camshaft was ground with. Most accessories will bolt up, though not all heads are machined for total interchange of these parts. Front timing covers and water pumps will interchange but a word of caution as there are many variations of water pumps and some covers do not have provisions for mechanical fuel pumps. A word of caution - Ford used whatever stock of parts was available, no matter what size engine family. A 1972 vehicle might just have a 1970 coded engine part. Additionally, factory service parts may be whatever is on the shelf, also not necessarily the current year. This means that before you commit money for an upgrade, that you know exactly what you have. In 1969, the 351 Windsor reached its' highest horsepower rating of 290 at 5800 RPM ==Ford MEL Series== In 1958 came the introduction of the MEL series engines. These were some of the largest and heaviest V8 engines Ford has ever built. ===383 cubic inch=== *Developed for the Mercury line of vehicles *Bore and stroke of 4.30" x 3.30" *Had a two year history

1965 *In one "souped up" version, the 430 was named Super Marauder and came with three two barrel carburetors *bore and stroke of 4.29" x 3.70" inches *Compression rations started at 10.5:1 but soon began to decline late in 1959 to 10:1 at 350 horsepower *The higher horsepower versions of the 430 remained within its first year of production with horsepower of 365, 375 and 400 *In 1959 the horsepower slowly began to be reduced, yet made 345 hp even with a slightly lower compression ratio of 10:1 *In 1960, the 430 cubic inch used a milder camshaft, producing 315 horsepower *In 1963 the 430 got an overhaul with new pistons and a four barrel carburetor, pushing compression to 10.1:1 and a horsepower rating of about 345 *It could be found in the 1958 Lincoln Continental convertible, rated at 400 horsepower and nearly 500 foot pounds of torque *Mercury also used the 430 cubic inch until 1960 ===462 cubic inch=== *By 1966 it replaced its predecessor, the 430 *bore and stroke of

2.09" intake and 1.66" exhaust valves *Cast iron intake manifold identical to the aluminum one on the police interceptor *Cast iron exhaust manifolds *Two-bolt main block *Between 345-360 horsepower ===428 Super Cobra Jet=== *Internal structure differences included LeMans type cap screw rods *The rod cap screws were shorter than the 427 to clear the block *Externally balanced *External engine oil cooler ==Ford 385 series== Although there were several variations to the engines of the 385 series, only two displacements were widely available, the 429 cubic inch and the 460 cubic inch. Both were introduced in 1968 and lasted until 1973. These engines were heavier and larger than the predecessor to the 385 series, the FE series. Additionally, Ford made a 370 cubic inch 385 seies. ===429 (Thunderjet)=== *Two bolt main bearing cap *Bore and stroke 4.36" x 3.59" *cast iron crankshaft *forged-steel connecting rods with 3/8" rod bolts *cast-aluminum pistons *hydraulic lifter camshaft *2.08" x 1.66" intake/exhaust valves *non-adjustable rocker arms *cast-iron intake manifold *4 barrel or 2 barrel carburetor *Was available in Ford and Mercury automobiles ===429 Cobra Jet=== *Four-bolt main engine block (with exception to some early 1970 models) *Larger cylinder heads used 2.25" x 1.72" intake and exhaust valves *Rocker arms were stamped steel 1.73:1 ratio with sled type fulcrums, threaded screw-in rocker studs and pushrod guide plates *The rocker arms on the 429 cubic inch Cobra Jet were also adjustable prior to 1969 *Cobra Jet used a Rochester Quadrajet carburetor atop a spreadbore cast iron manifold ===429 Super Cobra Jet=== *4 bolt main engine blocks *Forged aluminum pistons *Mechanical lifter camshaft *Adjustable rocker arms *780 cfm Holley four barrel carburetor ===429 Boss=== *All aluminum cast cylinder heads *Crescent type combustion chambers *Intake/Exhaust valves of 2.28" and 1.90" *Exhaust ports are "D" shaped *4 oil galleries *Identified by casting 429HP on block *Higher iron nodularity content with thicker cylinder walls *2 Versions of the 429 Boss existed, they were the 820-S and 820-T *Forged steel cross-drilled crankshaft *Forged aluminum pistons *Aluminum dual plane manifold with a 735 cfm Holley four barrel carb ===429 NASCAR=== *Larger Outboard bolts in #1 main bearing cap *Deck height was grooved for O rings *Larger machined reliefs for exhaust push rods *Longer street rods than the Boss 429/820-S type *Some blocks had full hemi design, others crescent type *Stainless steel intake valves *Magnesium valve covers and intake manifold ===460 cubic inch=== *Produced from 1968 to 1996 *Available in Ford, Mercury and Lincoln *Same as 429, but with longer stroke of 3.85" *During its earlier years, pre 1973, horsepower was rated at 365. After 1972 horsepower ranged from 208 to 275 *Intake/exhaust valves are 2.08" x 1.66" *Intake/exhaust valves for the Police Interceptor 460 heads (from 1973-'74) measure 2.19" x 1.66" *According to a previous owner, the 1974 460 police interceptor was rated at 425 hp and special carb. It also had a tank mounted electric fuel pump because it ran out of gas at about 130 mph with the regular cam driven pump, so it didn't have a cam driven pump at all. ==Ford 335 series== The 335 Series consisted of versions of the 351 and 400 blocks. It lasted from 1970 to 1975. ===351 Cleveland=== *canted-valve cylinder heads *bore and stroke of 4.00" x 3.50" *light weight block *one of the more desirable V8 engines Ford had to offer *two barrel or four barrel *From 1970 to 1971 the 351 had between 250 to 240 horsepower The 351 Cleveland four barrel came with dual exhausts, a higher compressions ratio, larger intake/exhaust valves and four bolt mains during the first year of production. The 351 Windsor, which belongs to the 90 degree V8 family, bears no resemblance or connection to the 351 Cleveland. As time progressed, the 351 Cleveland made less horsepower until its demise in 1975. ===351 CJ=== *Introduced in the fall of 1971 *mostly of four bolt mains, however there are some with two bolt mains *possessed a spread bore bolt pattern cast iron manifold *Autolite carburetor 4300-D *Horsepower varied from approximately 280 during the first year of production down to 265hp by 1973 ===351 Boss=== *Most desirable *only available in the 1971 Boss 351 Mustang *Four bolt mains *high nodular iron crankshaft *solid lifter camshaft with screw in studs *adjustable rockers *an aluminum four barrel intake ===351 HO=== In 1972, Ford rolled the 351 Boss over into the 351 High Output for the new year. Slightly less desirable than the Boss 351, the 351 High Output used the spread bore bolt pattern cast iron manifold for the Autolite 4300-D. With a milder camshaft, the output of the 351 HO was about 275 horsepower. ===351M and 400=== ;*Ford part numbers and casting ID codes for the internal parts of M-block (351M/400) engines, including [http://web.archive.org/web/20050729080035/home.earthlink.net/~bubbaf250/parts/parts03.html cam specs] *By 1975 the 351 Modified was issued with Cleveland heads and a two barrel carburetor *hydraulic lifters *a cast iron intake manifold *a two barrel carburetor The 351 Modified and the 400 which was introduced since 1971, are virtually identical with very few exceptions. Wikipedia's [http://en.wikipedia.org/wiki/Ford_335_engine Ford 335 engine] article indicates these 2 blocks are nearly identical, too. '''Australia''' manufactured the 351 Cleveland and derivative '''"302" Cleveland''' at Ford Australia Engine plant in Geelong, Victoria, Australia from 1975-1981. Although 302 Clevelands were being assembled in Australia from 1972 these were made up from imported US Cleveland blocks and Australian made crankshafts, heads, pistons and rods. It is beleived that the original Cleveland molds and equipment were shipped to Australia not long after the last motors were manufactured in the USA in late 1974. This included a large supply of 4V cylinder heads and 4MA and 4MAB crankshafts. Both Australian built motors (302C and 351C) used a unique Australian cast crankshaft, not the forged 4M cranks used in US motors. Australian made crankshafts have 351 or 302 cast into the front journal. Australian made high performance 351C motors (290 hp plus) used the imported 4MA or 4MAB cranks. All Australian 302C engines used cast crankshafts and 6" long rods and closed chamber heads (58-60cc chamber volume) made at the Geelong plant. 351 engines used an open chamber head of about 74cc. All heads were of a small port (2V) size, even for a 4 bbl option. 4V heads (US made) were available on Australian GT and GTHO optioned 351C motors up to about 1975 when supplies eventually ran out. 2 bbl and 4 bbl carbs are used on both motors, however after 1976 Carter Thermoquads of about 800cfm rating were used instead of the Autolite carb, this included the 302C. 302C engines supplied with a 4 bbl Carter Thermoquad carb after about 1977 had a uniquely modified spreadbore type manifold which feature a reduced plenum area for increased throttle response. These 4 bbl manifolds were not used on 351C engines. The OEM 2 bbl carb supplied standard on 302C engines was a Stromberg not the Autolite as supplied in the US on 351C. This carb was adapted with an aluminium spacer plate. Australian made 302 and 351 engines were used in all locally manufactured vehicles that had a V8 as an option. This included but not limited to Falcon, Fairlane, LTD, F100-F350. Last Australian made Clevelands motors were installed in 1982 XE Model Fords. Sadly it is common for Australian made Cleveland blocks to have severe core shift. Overboring passed about 0.020" may be a problem. ==Ford Y-block series== ===239 cubic inch=== *Cast iron crankshaft, intake and exhaust *Cast aluminum pistons *Mechanical camshaft *Available in Ford cars in 1954 and 1955 Ford trucks === 256 cubic inch === *Used only on Mercury vehicles and in F-series Ford trucks *Compression ratio of 7.5:1 *161 hp at 4400 RPM === 272 cubic inch === *Two versions available for 1955 *Two barrel carburetor with 7.6:1 compression and 162 hp *Four barrel carburetor with 8.5:1 compression and 182 hp *In 1956 horsepower varied with automatic or manual transmission *In 1957, the 272 cubic inch reached 192 horsepower === 292 cubic inch === *First introduced in the T-bird and Montclair *All used four barrel carburetor in 1955, but horsepower varied, but average around 200 depending if equipped with a manual or automatic transmission *Bore and stroke: 3.75" x 3.30" *Following years were produce less horsepower, until its' demise in 1964 === 312 cubic inch === *Largest Y-block *Bore and stroke: 3.80" x 3.44" *Two versions were introduced, both with four barrel carburetors and dual exhausts *Introduced once again in the 1957 T-Bird, it gained critical acclaim for producing over 300 horsepower while equipped with a Paxton supercharger ==Flathead== *[http://www.btc-bci.com/~billben/flathead.htm Flathead engines] == Lincoln family == === 317 cubic inch === *Cast nodular iron crankshaft supported by five bearing journals at 2.62inch *Rod journals measured 2.249" *8.0:1 compression ratio and 205 hp at 4200 RPM *An improved Holley carburetor, high lifter cam, dual diaphragm distributor and freer flowing exhaust === 341 cubic inch === *Last only for 1955 *Increased bore to 3.94" *Compression ratio of 8.5:1 with 225 hp at 4400 RPM and 332 ft/lb of torque === 368 cubic inch === *Introduced in 1956 *Increased bore and stroke to 4.00" x 3.66" *285 hp @ 4600 RPM with 402 ft/lb. of torque *Compression ratio is 9.0:1 *Larger exhaust valves at 1.64", bigger fuel pump and dual diaphragm distributor *Black painted valve covers and air cleaner *Following production year had slightly revised enhancements including 10.1:1 compression, Carter four barrel carburetor and a spin on oil filter ==Related resources== *[[Ford part numbers]] *[http://whatareyouworkinon.com/content/ford-casting-numbers Ford casting numbers] {{youcanedit}} [[Category:Engine]] [[Category:Identification and decoding]] [[Category:Ford]]
