  • L10 Change on 65 HiPo Head

    So far, it appears that 1966 289 HiPos were L9 engines, and 1967 289 HiPos were L13 and L14 engines. (L5, L6, L7, and L8 apply to 1965 289 HiPo engines.) However, L13 does not mean that L10 (small valve springs), or L11 (rail rockers/round holes on Windsor engines), or L12 (rail rockers/round holes on Cleveland engines) were encorporated. 1967 began with L13, and L14 replaced the smaller valve springs with larger ones, which was not applicable to the 289 HiPo. In summary, I don't know of any 289 HiPo engine tags with L10, L11, L12, or L15 (emissions driven changes). If there are, I would be interested in hearing about it.

  • pistons

    The correct compression ratio for the 1965 289 HiPo was 9.8:1. HiPos always had valve reliefs. Early 1965 225HP 289 4Vs used flattop pistons without valve reliefs and were true 10:1 compression engines, but mid-year the pistons were changed to include valve reliefs, so comression dropped to 9.8:1 -- same as the 289 HiPo. The pistons were not the same. The HiPo piston reportedly used a higher strength aluminum material. Today, materials are much improved, so the same piston can be used in both applications.


    P.S. The 10.5:1 compression ratio was associated with the small-chamber 1963-early 64 heads.

  • 63 WATER PUMP I.D.

    On page 3-46 I show the C2OE-8505-C water pump. Your C3OE-8512-A impeller crosses to the C2OZ-8512-A part number, which Ford indicates is the standard 4.7" impeller. But, your description of 3.9" would seem to indicate a HiPo impeller. A picture of the impeller and casting number might help. According to Ford, the early HiPo impeller was part number C3OZ-8512-A with a engineering number (probably the same as the casting number in this case) of C2OE-8512-B.

  • 65 Fuel Canister Mask

    Oops! The S is there, but it is under a layer and could not be seen. The red color was just for effect. I continued to refine the mask. The difficulty was in decisions about the stars and small Genuine Parts letters. If you look at any canister close up, those letters and the stars are really bad. I took a middle-of-the-road approach. I had a good idea what the letters and stars were supposed to look like, so I first made them that way, then deemphasized the corners by making them softer. I figured that the application with the mask would further degrade the crispness. I will say that this mask is much truer to the real thing than what I have currently seen in reproduction. Here is the mask and a close-up of the star area.

  • 65 Fuel Canister Mask

    The work on a mask has already been done. Using original canisters, the proper fonts were created to make the mask as close to the original as possible. The greatest difficulty was in the small letters and the three stars. The mask attempts to duplicate these in a realistic way as the original stars and small letters were not crisp. I have this mask in CorelDraw as a vector graphic. I can save it in other formats if someone wishes to make a mask. The color red is just for effect.

  • 1965 alternator markings

    Lots on ink stampings, but were they put on by the factory when the alternators were produced? That is the question. The service replacements from 1966 and on were, both those with pulleys (10300) and those without (10346). This would include those marked for 1965. But, for those originals that were on the 1965 cars as they left the factory, were they stamped? That is the question. Mercury says they started stamping them for the 1966 cars. In my years of goig through junkyards, I never found an original 65 alternator stamped. Not saying they were or were not. Really trying to find a case of a absolutely known example of a factory original 65 alternator (not a service replacement for 65) with a stamping.

  • 64.5 Generator Question - need help

    The generator number was specific to the installed pulley. A C3OF-10000-B generator number would have come with the C3OF-10130-B pulley. There were two styles of pulleys used in 1963 and 1964. One was stamped C3OF-10130-B and the other C3OF-B.


    Stamp placement varies, but the attached PDF file will help you place it in the right area. Also, the included graphic is an accuracy redition of the stamping.

  • 1965 alternator markings

    I searched but did not see a topic on this. The question is, did factory original 1965 alternators come with ink stampings. Mercury stated in a 1966 TSB that all 1966 cars would have color ink stampings on the alternators. I know that service replacement alternators of 1966 and later also had the stampings for 1965 applications. The base number might be 10300 (with pulley) or 10346 (without pulley). But, the question is, when the cars left the factory in 1965 with their original alternators, did they carry colored ink stampings? Does anyone have a picture of a known-to-be-original, factory-installed 65 alternator on a 65 car with an original ink stamping? Every 65 I have come across that is low-mileage and unmolested, I have not found an ink stamping.

  • Flywheel

    So, as I understand it, your C6ZE-6380-A, 6J21, C7ZE-B flywheel has a Brinell marking. The C7ZE-B identifies it as a standard 289.


    In investigating 63-64 flywheels, I have not yet found any consistency in hardness testing. I have found a few flywheels with what looked like a possible Rockwell hardness test with a cone impression, but it could be a casting flaw. At any rate, I found the same mark on both a HiPo and 260 flywheel (both C3OE-6380-B castings), so it is not germane to the 289 HiPo distinction.


    The C3OE-6375-C print calls for identication by painted part number or equivalent marking in the area at the The only difference is in the imbalance. The C6ZE-6375-A print calls for a steel stamp prefix and suffix of the flywheel assembly number in .18" size letters to a .02" max depth in the area of the outer perimeter. Neither print mentions instructions for performing any hardness testing on the casting of the flywheel. Both do mention the cast iron is to have a Brinell hardness between 179 and 235.


    Please keep collecting information. So far, it seems that the C6ZE-6380-A castings for HiPos will be stamped C6ZE-A or C7ZE-A. The Brinell hardness test might be incidental. Info I received from someone who talked to persons in the engine plant at the time indicated that the casting material for flywheels was the same for 289 HiPos and standard 289s. The print agrees.


    For the C3OE-6380-B casting, it would appear the primary identifier was the color of the paint. If so, need to determine the color for standard 289 flywheels. I have confirmed circled C markings on 63 HiPo flywheels, and circle A on 64 260 flywheels. But, on standard 289 in 64 and 65, I have not found circled letters nor hardness markings. Need lots more additional information on any C3OE-6380-B casting for 63-66 production 289s. Specifically, I have yet to see a standard 63 389 flywheel (only found on 63 Galaxies late in the year); or a 64 289 HiPo flywheel. Need more data on 65 289 and HiPo flywheels as well.

  • 64.5 Generator Pulley

    If you can get a hold of my book called "Mustang & Ford Small Block V8, 1962-1969" you would see pictures of each type and the identifcation markings for each. The book will probably answer a few more questions you didn't even know to ask:-)


    But, so that you know this is not a shameless commercial plug, here are the pictures:
