Correct, but it wouldn't be the other way around (302 in a 289 block), especially since there were no '67 302 blocks...
289 production began in Ford's Cleveland plant. In mid-year 1966 the Windsor plant also began producing 289s. The casting numbers for these were (C6AE-6015-C with a "289" and "WF" in the lifter valley. In 1967 both Cleveland and Windsor produced 289s using earlier year casting numbers but with updated date codes. These two blocks were interchangeable, but there were probably some minor differences. Near the end of the 1967 production run, Cleveland ran out of 289 blocks and substituted their new 302 block, C8-OE-6015-A and marked with 302 in the lifter valleys. This block wasn't intended to see action until 1968. Note these 302 casting numbers returned to the intermediate size Ford or Fairlane lineage. Hence, a late model 289 coming from the Cleveland plant might have a 302 block with 289 innards. The Windsor plant had an abundance of 289 blocks for 1967. In 1968 Cleveland only made 302s, while Windsor continued with the 289s. It appears Windsor also tooled up for 302s but the plug was pulled before they got to make any. They did however, design and produce a 302 block that was used on 289s after the stock of 289 blocks was depleted. The number was C8AE-6015-B with 302 marking in the lifter valley. At the very end of the model year some additional 289 blocks must have been discovered as the older C6AE-6015-C blocks appeared again. In 1969 Cleveland continued with 302 production. Windsor dropped 289 production and took up the 351. In 1970 Cleveland came out with its newly designed 351. In short: C8AE-6015-B is a 302 block from the Windsor plant that was used in 1968 on a 289. C8OE-6015-A is a 302 block from Cleveland from a 1967 289 or a 1968 or later 302 (check date code). There is no code stamped n the block itself that can be used to identify the cubic inch displacement of the block. Casting numbers can be helpful, but some blocks used several different casting numbers, and in some cases, one casting is not interchangeable with the other. Engines are identified by a tag attached to the engine. This tag is used on all late 1964-1970 models and located under the coil attaching bolt. On the tag is the displacement, assembly plant, model year, change level, engine code (useful in identifying high performance engines) and date of production. This tag is easily lost or replaced with a fake tag, so don't rely solely on the tag for identification.
My cousin's had 302 stamped on the block where the rubber intake gasket seals. It was stamped, not cast, as in its very possible that only a few were done. He bought the car from the original owner with around 30K on the clock, never been into. Original plugs, wires, cap, etc... Still had the original spare in the trunk.
The tag on my 302 has been removed somewhere along the line but there is a number stamped on the block at the very rear on the center line. Unfortunately, it is not stamped well and appears to be "OP104688". Does that number ring any bells? If so, what does it tell me? There is no tag elsewhere on the engine.
This is great. Bringing back a lot of memories. I used to be a walking small block ford manual but have forgotten quite a bit now. I must have read my How to Rebuild your small block ford book a hundred times. Even had the combustion chamber volumes memorized. Came in handy wrecker hunting. Excellent book by the way if it is still out there. Recommend it highly. I'd sell mine but its really worn and dirty.
There was never a tag on the block. The only place there was ever a tag was on the intake manifold. What are you trying to find out? If its the year of the engine then look on the passenger side of the block teard the rear about 1/3rd the way up the side and you will find a boss with a number cast into it. It will tell you the year of manufacture and what the car was originaly produced to be put in, followed by the part number of the engine. I hope this helps, if not then we need to know what you are trying to find out about your engine so we can help you.
talking about 302 / 289 I walk quickly to make sure I got a 302! funny take at look! I have 302 yahoo:
I am aware the tag(s) were not part of the engine but secured in a couple of places (coil, valve cover or dipstick tube). I've foung no tag anywhere but perhaps I should have provided more info. The car is a 1933 REO Roadster body, supposedly over a modified Torino frame, Ford Disc brakes, steering, C4 trans, rear end and suspension. Other than having a 2 BBL Keith Dalton (Holley) racing carburetor and Mustang cast Aluminum valve covers, the engine appears to be unmolested/un-modified (with the exception of the timing cover that looks like it has been replaced). It runs out quite nicely but I am curious if it is really a 302 and what year it was manufactured. I am not going to go into the engine just for that and am looking for information from the experts.
cant agree with this one.... ive had several over the years and ive had some that have an engine tag bolted to the front of the driver's side head. ive got one downstairs if need be shown...
man that's a dirty engine.... lol. just check the lifter galley, ive seen some stamped 289 or 302 :Handshake
man that's a dirty engine.... i know! I remove all parts of the engine, to give them their first bath
I ca say one thing about Ford 289,302's and 351w with certainty. If you think you know all there is about them you can bet something will eventually throw you for a loop. There were too many people working the assembly lines for everything to be exackly the same on all of them. When model year changes came along and they had an abundance of the old engine I hate to think of some of the things they might have done to use up inventory. The books are not as accurate as people would like to believe either. Want to start a good debate? Ask what the FE stands for concerning the so called large block Ford. lol I have seen 302's with 3 bolt balancers and timing cover dip sticks. Head water passages will mess you up between a 289 and a 302-351w also. clint
