Topic: 5 bolt to 6 bolt changeover

[Dan Case]

Do we know if Ford was using both Cleveland and Windsor foundries in this time period? I could not find the information.

Based on what is published by Bob Mannel:

Implied that all 260/289/HP289 engines were produced in Ford's Cleveland Engine Plant #1 through mid-1966; with one sentence that indicates High Performance 289 engines were only made in Cleveland for any model year.

289 'standard' engines were made concurrently in Cleveland Oho and in Windsor Ontario mid-1966 and 1967.

It does not appear to have the 64 telltales, but I will try to look at it in more detail now that it?s on the engine stand.

Also - The fellow with the D-code that was assembled the day before mine, messaged.  Said he looked and his is definitely a 6-bolt also.  Can?t see casting date though.

Of course you misspoke since we don't know when any of these cars were built. Must have meant they were scheduled a day apart. Could have been three weeks or in some rarer examples longer. when if comes to real build date.  but its something.

Actually, not at all. The guy with the D code....that engine was stamped July 23 as an assembled date.  Mine is stamped July 24th assemble date.  Talking engine assembly dates and not full vehicles.

Just so I am clear, I am also talking about the stamping on the block up front near the timing cover.  That is engine assembly date, correct?

Thanks for making it clear that you were "talking" about engine dates not car assembly dates in your prior post. Yes that is the engine assembly date  still trying to research and determine exactly how much of the engine that indicated but that is another thread and for another time

Interesting. Did the engine have a 1963-64 model year design oil pan or a 1965 model year design oil pan. Was it configured for a generator or alternator (different dip stick tubes and dip sticks) plus hole size in the RH cylinder head for a mounting bracket bolt?

I did get a chance to check and it has the 65 style oil pan, dipstick tube/stick, and configured for alternator.  And interestingly, it has the Eaton style P/S pump with a remote reservoir. Then A/C on top of the P/S pump.  Pulleys are all 1965-style, no castings.

Thanks.  👍

I?d love to hear what you have compiled on your engine assembly research.

Thanks neat and interesting.
