Ford Engine Block Serial Number Identification

Ever wonder what dimension engine you possess? If therefore, your not the only one. To the unskilled enthusiast all little sixes look identical, however there are minor distinctions which can end up being easily seen if you understand what to look for. In this content we'll cover a bulk of the differences, for motors produced in the USA, even though you just require to understand three to recognize the engine sizeWhile Australian and/or Argentina built motors are related to their Us all counterparts, they possess their own unique collection of distinctions. Some of these differences are usually the exact same as their Us all counterparts, while numerous are not really. For example, all US-250ci motors got a reduced mount starter, while the Australian and Argentina 250's got a high mount beginner. Consequently exhaust headers created for an Australian 250ci actually will not really fit the US-250ci, or vice versa.

Another example would end up being the oil water pump, while the oil pump get is the same dimension, the bolt styles are various. As a result the oil pumps are usually not interchangeable. The People-200/250ci distributors and canister heads will match an Australian 200/221/250ci Pre-Crossflow, ánd vice versa. Nevertheless the AU-250ci actually Crossflow suppliers and cylinder heads are exclusive to the CrossfIow and will not really interchange with the US-200/250ci engines. One final example is the oil pan, also non-interchangeable, as the Foreign and Argentina 250ci oil cookware (and pads) are usually one inches narrower in width.

Ford Engine Block Serial Number Identification Codes

The list goes about.General Explanation: The Little Six (or Falcon Six), overhead control device, inline 6-canister engine was launched in 1960 with a team metal block and cylinder head. All US cylinder heads incorporated an essential one clip or barrel intake manifold, more typically identified as a journal consumption. The crankshaft and flywheel are dynamically well balanced, and the crankshafts are usually installed with a harmónic damper, which is usually often called a balancer.Mass Codes: Block out codes were an attempt at a cást-on block idéntification system can become discovered on the street draft pipe mounting manager.

Block requirements were in use up to 1964, or right now there about, after that Ford switched to little metal labels that were bolted to thé engine block. Thé block codes had been as follows 144ci: “N”, 170ci: “T” Take note: 200/250ci engines, and some 170's i9000, did not really have got block rules, as steel tags had been used rather.Below is certainly an illustration of the labels used on engines from 64 on. This will be the tag from a 1969 250cwe engine. They are usually quite equivalent to those found on carbs, back ends and transmissions. They are usually usually very precise, and were normally installed on one of the coils bracket bolts. However they are usually commonly dropped or left off after a rebuild. 250 is certainly the displacement óf the engine.

69 is usually the design year of the engine. 1 is certainly the transformation level. 8-T is usually the yr month produced (68-December). K45-S is the engine program code number.The engine code number change level were intended to aid engine stores when they purchased components. In actual practice really few paid any interest to these figures, as they just served to confuse the purchasing process. Therefore we will not talk about them in higher fine detail.

Four MainSeven MáinMain Bearings: All 144/170ci, and 200ci pads prior to middle '64, got four primary bearings. While the 200ci from middle '64 onwards, and all 250cwe blocks, acquired seven mains bearings.Rods: All 144/170/200/250ci engines have cast H section link supports, with the exemption those built in 78-79, which utilized either thrown iron, forged metal, or nodular metal.Heart stroke: The 144ci engine has a 2.50 inch stroke, while thé 170ci has a 2.94 inches stroke.

The 200 has a 3.13 in . stroke, while thé 250ci engine has a 3.91 in .

stroke.Pistons: AIl 144/170ci engines have throw aluminum smooth best pistons with a 3.50″ size, while the 200/250cwe engines used a dished pistón with a 3.68″ diameter. The meal size has been usually 6.5 cc's, however a 13 cc dish was used in California motors, which lowered the data compresion ratio and decreased emissions.Cylinder Bore: All 144/170ci engines have got a 3.50 inches cylinder bore, whiIe the 200/250ci have 3.68 in .

cylinder bore.Cylinder Heads: Depending on the creation yr, the chamber size, control device size, intake size (manifold volume), and carburetion varied significantly. Carb bores had been as follows: 144/170ci actually: 1.325″, early 200ci actually: 1.500″, later 200/250ci: 1.75″ (all were 1V carbs).Lifters: '60-'62 144/170cwe engines acquired strong lifters, '63-'65 144/170ci engines got both designs depending on the season and design, while '66-UP 144/170ci engines acquired hydraulic lifters. AIl 200/250ci engines got hydraulic lifters. Illustration: The '64 Falcon 170ci experienced hydraulic lifters, whiIe the '64 Ranchero 170ci acquired solid lifters.Rockers: '60-'62 144/170ci actually engines acquired variable rockers, '63-'65 144/170ci motors experienced both changeable and non-adjustable rockers, depending on the 12 months and design, while the '66-UP 144/170ci actually engines had non-adjustable rockérs. All 200/250ci motors got non-adjustable rockers.

Example: a '64 Falcon 170ci with hydraulic lifters got non-adjustable, whiIe the '64 Ranchero 170ci with solid lifters acquired adjustable.Suppliers: All 144ci engines, and 1960-middle'64 170ci motors, got a 1/4″ hex drive-shaft. The middle'64-UP 170ci engines, simply because properly as all 200/250ci engine,s got a 5/16″ hex drive-shaft. Note: This is certainly just a rule of thumb, as it may differ based on the calendar year and design type.Beginners: Nearly all 144/170/200ci motors had high mount beginners, which had been installed above the oil pan rim, while the 250ci engines had low mount starters, which had been mounted below the oil pan rim.

221, 260, 289, 302The 221, 260, 289 were originally made for the Fairlane and produced just in the Cleveland engine seed from 1962-1965. The 289 sending your line number for all 289s has been D4OE-6015-C (later on an F suffix). In 1965, this number had been changed to Chemical5AE-6015-E for the 289 2V, 4V and Hi-Po (note the transformation to full dimension Ford designation and 6 bolt bell enclosures).In mid-yéar 1966 the Windsor place also began creating 289s.

The spreading amounts for these had been (C6AE-6015-C with a '289' and 'WF' in the lifter area. In 1967 both Cleveland and Windsor produced 289s making use of earlier 12 months casting amounts but with up to date date requirements.

These two blocks were compatible, but there had been possibly some small differences. Near the finish of the 1967 production work, Cleveland ran out of 289 obstructions and substituted their brand-new 302 block, D8-OE-6015-A and ski slopes with 302 in the lifter valleys. This block wasn'testosterone levels meant to find activity until 1968.Note these 302 casting numbers came back to the advanced dimension Ford or Fairlane family tree. Therefore, a late model 289 coming from the Cleveland place might have got a 302 block with 289 innards.

The Windsor place experienced an plethora of 289 pads for 1967. In 1968 Cleveland only produced 302s, while Windsor continued with the 289s. It seems Windsor also tooled up fór 302s but the put was drawn before they obtained to make any.They did however, design and create a 302 block that has been used on 289s after the share of 289 hindrances was depleted.

The number has been M8AE-6015-B with 302 marking in the lifter area. At the pretty finish of the design calendar year some additional 289 blocks must possess been found out as the old Chemical6AE-6015-C hindrances appeared again. In 1969 Cleveland continuing with 302 creation. Windsor fallen 289 production and took up the 351. In 1970 Cleveland arrived out with its newly designed 351.Id shórt:C8AE-6015-B is certainly a 302 block from the Windsor herb that has been utilized in 1968 on a 289.C8OAge-6015-A is a 302 block from Cleveland from a 1967 289 or a 1968 or later 302 (check out date program code).There is certainly no program code rubber-stamped on the bIock itself that cán end up being utilized to recognize the cubic inches displacement of the block.

Spreading figures can end up being helpful, but some hindrances used many different sending your line amounts, and in some situations, one sending your line is not really interchangeable with the various other. Engines are determined by a tag attached to the engine. This tag is used on all past due 1964-1970 versions and located under the coils affixing bolt. On the label will be the displacement, set up plant, design year, shift degree, engine program code (useful in determining high functionality engines) and day of production.

This tag is very easily dropped or replaced with a bogus tag, so don't rely solely on the tag for identification.Canister HeadsCasting figures for cylinder heads may change from calendar year to year. For illustration, the program code may be throw as C6ZZ-A in 1966 and Chemical8ZZ-A in 1968 also though they are usually the same cylinder head. Special minds are required with emission controls from 1965-1966 for the emission program to function properly.Starting in 1967, all mind have provisions for emission handle systems. Casting numbers are usually the same or almost the exact same as the part number.
