1965 289 HP C5AE-E blocks

Very little difference between Hypo and std block... 289's are nice however date coded 427 S.O. has waaaay more value.

I don't think Ford made the 260 in '65... that was done with in '64 when the 5-bolt block ended. The 260 has a 3.8" bore, so you have a 289, with 4" bore, and the engineering number for the 260 is C3OE-6015 E, whereas the '64 289 is C4OE-6015 E or C4AE-6015 E. The hipo motors use the same blocks, thus the same numbers, but the main caps are different.

There were some other differences, too....for example, there was a circular "weight" on the crank of the hi-po, at the area between the first crank throw and the block, but that's not why I called .

I've often wondered if there isn't some way to replace the less than effective main caps on the 289 series with better ones....it seems to me somebody ought to sell 4-bolt main caps that could be line-bored to the correct ID and a machine shop could tap the main webs for the outer bolts.

Of course, that's too simple....it can't be an original thought, so maybe someone does.

Anyone know anything about this?

BTW, I have located what I think is a '65 Galaxie with a 289 and a 3-speed manual (3 on the tree). I thought it would be a "5-bolt block", but do I understand correctly that if it is a 289 or a 1965, it will NOT be a 5 bolt block?

Only way to be 100% sure is look at the back of the block, 6 bolt blocks should have started with the 1965 production, but a few may have been 5 bolt blocks as production changed over, they are rare,but there are some out there.........

Yes, but he was asking about the block... not the crank/counterweight.

Well, the stock main caps aren't all that bad. The 289s spin up pretty good and hold together well... within reason of course. But if you need more, you can get heavy-duty 2-bolt aftermarket main caps at any good speed shop. Here is a link to some Dart 4-bolt ones, though not sure that they would work... check with your machinist:

No, as I mentioned above, the 289 came in a 5-bolt variant in '63-'64. If it is a '65 however, it is the 6-bolt version. Ford quit making 5-bolt production 289 blocks at the end of July 1964. They did continue making 5-bolt service parts into '65... hope that helps. All you need to do is look at the engineering number. If it is a C5AE-6015 E, then you have a 6-bolt block. See my post above for the 5-bolt block engineering numbers. The date code, right above the engineering number will tell you when it was cast. Ford began casting the early '65 6-bolt blocks in mid '64, and the earliest one I've seen was cast in July of '64, maybe they made them even earlier...

Keep in mind that it may not have the original engine in it...

Good luck with it.

I am new to this so I wasn't aware of your previous discussions...
I am also aware that there are few differences between blocks. That is what led me to this site where I thought I may get some info. Thanks for the help and the value comparison, as I now know that a 427 is more valuable than a 289.
