    Kapp the 30 below the 352 is just the block mold number. The 352 was just an identifier used on the block besides the later reverse 105. Besides checking the cyl bore you also want to gap the cyl wall cores. This will further help to tell what block you have. Sonic checking is the absolute best way but this is a quick and easy identifier. I can fill you in if interested.

    Snake, I figured you meant 66. I've done the same many, many times. Fingers faster than the brain in my case. LOL. G.

    As always, your help is much appriciated. I just pulled the oil pan off to check out the crank and it has the "1U" marking on the second weight from the rear of the motor. Just wanted to verify what Snake said. If it is a 410/428 crank I will be very happy.

    Jamie if the "A" is on the rear of the block as you describe good chance the block is a 428. DIF is for Dearborn Iron Foundry where the block was cast. You can then knock out the freeze plugs and gap the wall cores to see if it's a 428. A 13/64" drill bit shank will fit snugly between the cyl wall cores for a 428 and 17/64" bit shank for 390 cyl wall cores. This is commonly know as the drill bit test and you can convert the 64" to better suit you bit sizes if needed. This is just the standard measurement for the test. This will confirm what cyl wall molds were used inside the block. The C8-H heads were used on std 428's (not CJ/SCJ) and also 352's and 390's. So it's a pretty common head and could be original to the engine if the date codes for both jive with the block. If you determine the block is indeed a 428 look for a "IU or IUB" marking on the crankshaft. This will confirm a 3.98 stroke 428 crank. You can of course meaure the cyl bore for a 4.13 428 or 390 4.05 cyl bore. The drill bit test will back up your bore measurement readings hopefully. Also keep overbore in mind when measuring cyl bores. Get the date code off the block and heads if possible. Look for a number/letter/number(s) sequence below the oil filter adapter mounting pad on the block. Also above the C8 casting number under the valve cover area between the center two valve springs for the heads. Sorry to write a novel here.

    Hey Denny hows things? Those heads were used on the 410's. But also 352, 390, and 428. And the block C6ME-A is listed for a 410. But also listed for a 390,428,330HD and 360. So check the bore and wall cores inside the freeze plugs to confirm. Also look for "IU" on the crank for a 410 crank. Should be on the 7th counterweight from the front. The 6L10 is the date code of 66/Nov/10th. The "A" offhand think was just an internal identifier but not positive. What is the date code on the heads? Should be between the center two valve springs. The original slugs would have 410 on them also. Also on the heads I have two listings for that casting. First the 66-68 390 with 67-70 cc heads and thermoactor. Second the std listing for the 67 352, 390, 410 and 428 with 71-74 cc heads. Let me know what else you need. G.

    thank ffr428. i got into the crank last night and the only markings i found on the crank was 2u on the 2nd or 3rd weight.it must be a 390 , ill check the cyl tonight. i was thrown off by all the diffrent casting numbers , on on cyl head by the plug hole has 21 and the letter w and the other has a 5 and the letter e.there is also a large 2 above the casting number on the block. the a is on a milled ear that looks as if it was used to hold the block during assy. just above the starter and it can be seen with the engine in the car

    Have a question. I had a fellow come into my shop the other day and wanted me to do some front end work on his 54 ford truck. He like most of us are on a budget and wanted to save a little money so he asked if I would take a motor for a partial trade out I said yea sure exspecting to see a flat head or six in there when i raised the hood there was an FE motor under the hood. Hmm I said well with my luck it is a 352 well not this time. It appears to be a 390 numbers read C3AE and then under them it has 6015H. I know that it is a 63 and as some of the info tells me the A stands for fairlane or galaxie ( cant remember) and we all know the E is for engine. Now what I need to know is what does the 6015 mean and the what about that H. I know that the engine has an A but the engine has THUNDERBIRD on the valve covers and also has an S on the manifolds indicating TBIRD could the A code motor have been used in a TBIRD. The only reason that I ask this is becuase it all looks like it has not been tampered with and the numbers all indicate 63 plus it still has the keeper locks on the exhaust manifold bolts. Ant ideas? Thanks

    The C3AE-6015-H was the service block for the 62-63 390 PI. It's a hyd lifter block and is the service replacement for the C3AE-6015-E solid lifter PI block. The H block was used in either std 390 or 390 PI applications as a multi purpose block as it was drilled for hyd lifter oiling. The lifter oil galleys were plugged if solids were ran...or not. The 6015 number is just the casting number for a std production block. Serivce blocks used a 6010 part number. The Thunderbird VC's came on all FE's back then not just the Tbirds. It's also very possible the H block was a regular production block then after. My resources indicate a service part tho. But the best was to tell is grab the date code off the side of the block and compare it to the head and intake date codes. You can also check the blocks final machined date on the left ear by the head deck. That is stamped in after the blocks are machined. The blocks date code is on the left side above the oil filter adapter. The head date codes are under the VC area between the center 2 valve springs. Intake date code if iron should be by the thermostat or dizzy area. If aluminum it may or may not have a date code. What is the casting number of the heads? It's between the center 2 spark plugs. C3AE-6090-C?

    Pretty much what FFR said... my 64 Tbird has a C3AE-6015 H block in it, painted black, gold "thunderbird" valve covers. 4.05 bore x 3.78 stroke, hydraulic lifters. At this point in time I'm assuming its either the original block or a factory replacement because of the date code by the oil filter adapter.

    Yep! a "1U" code means it's a 3,98"stroke crank...so a 410/428 crank
    Going sideways through a bend isn't considered normal or even sane, so that's the way I like it!

    eh...sorry Snake...to add to your pain of not having a 428, but eh...you mean a 390 bored .060...'cause a 410 was a 390 block with the 3.98" stroke crank, nothing more...(well...a little more)

    390 bored .060 and with 3.98" stroke makes 422...a non-stock cube combo
    a bored 390 with an .060 overbore makes a total of 4.110" cylinder bore, wich comes pretty close... but some 6 cubes short of being a 428
    (my bird has it's bored and stroked 390-->422 right now)

    ok FFR 428 the plot thickens or at least the confusion does. The oil pump has a B9AE on it, the crank has a C3AE-E and a D stamped on the front wieght and a number 10 cast in to the crank. the rods say C1AE the main caps say C2AE and the block below the oil filter says V S (and then bellow) 3026 the heads have a 3C29 date and between the plugs 6090C and then in larger numbers 40. the D on the crank mean and the 6090C and 40 on the heads. Why were all the bottom end parts different as far as dates was it peice mealed engine or what?

    No just the opposite it all sounds pretty original. The C3-E crank is a 390 crank used from late 62-early 64. The rods and maincaps also correct. Those rods were used for a few years and into 63. The C2 on the maincaps can be found on all FE blocks except the 427 until the early 70's. And the 3026 I bet is a 3C26 and the date code of 63/March/26. So double check that the 0 is a C. Heads 63/March 29th C3AE-C std bread and butter FE lowriser head used ath the time. There are lots of other letters and numbers and stampings etc...most of which pertain to the mold numbering system the Dearborn foundry was using. Some of the stampings are marks for finished parts or to tell the guy down the line these parts are different etc... The B9 oil pump I'll have to check but I'll bet the rocker stands are B9 parts also. LOL. Ford would not change the casting number on the part for years sometimes. They would change or update the part number in the books while the part itself and it's casting number was not changed at all. So to me it all sounds very original. Good deal!

    Alright this a good thing the block looks great I dont think that the motor has ever been torn down. It still had the metal head gasket with ford numbers on it and felpro gaskets on the intake. I know where there is another 390 to stick back for rainy day. Ok you guys have been such a help I need a favor. The 70 boss car that I have bolonged to the best bud I ever had. He was killed in a motorcycle wreck august before last and what made it eaven worse we had lost a mutal close friend in august two years before that. He and I were starting on a 70 boss 302 grabber green flat top car. After we had torn down the engine we found that the block was a standard (non boss) 302. Every thing else in the engine was boss except that. We got the car stripped and were waiting for the sand blaster to call and let us know he was ready for the car. Well in the mean time marty was killed leaving behind a wife and four kids. His job mandated that he have good life insurance and he had his finances pretty squared away. The only boy mitchell is 14 who I take alot of time with we still ive right across the street from them. He is interested in building the car. Marty and I had already restored another 70 boss that he had sold. He kept the money from that car and had planned to use that to restore this one and make an all original driver out of it. His wife is all about having this car restored and wants me to do it for them. I have a problem. I cant find another block for the car and I know there has to be one out there that someone would part with to make this car happen the way marty would have wanted it to. Thanks
