My 53 parts truck has a 289 in it, that much I can figure out. I was wondering what year it was from. The casting # above the starter is C5AE-6015E and below that is 4G29. Anybody know how to decipher these numbers? I was told it was a 289 Hipo, but I wouldn't believe that unless numbers prove it

 

July 29, 1964 is the date of your block. Factory-installed 289 High po engines had the vehicle serial number stamped into the righthand side of the block near the battery's negative-cable attachment point. The casting # is correct for a hipo, but it could also be a regular 289 as well. Hi-Po's used wider main caps and larger rod bolts as well. -Andrew

 

I know nothing.

 

It's possible the engine could be a hipo, but not probable, since they didn't make near as many as standard 289's. Aside from finding the stamped vin from the original vehicle, which wasn't done 100% of the time, there's no external clue to a hipo block. Nothing in the casting numbers will identify one. In fact, the blocks were the same whether they were for standard or hipo engines. As noted, hipo engines had different main caps, connecting rods, camshafts, heads, and a few other specific, bolt-on-type parts. Even the crankshafts were the same, but the cranks used in hipo applications were hand selected and hardness tested to find the 'cream of the crop' castings.

Have you ever pulled a valve cover? Hipo heads have a cast-in valve spring cup, but that is the only difference from the standard. They all have the same ports and combustion chambers as standard heads of the time. About the only real external clue is the harmonic balancer. And that is only if it hasn't been changed. Standard 289's are rather skinny, where the hipo is considerably thicker.

One more question, does your block have 5 or 6 bellhousing bolts? A late July casting was right around the changover time.

Here's a website link that may be helpful with your identification.

a couple of other things to help tell the difference between a plain jane 289 and the hi-po (or K code as they are better known as)

- the 289 hi-po had solid lifters and screw in rocker studs. other 289's had hydraulic lifters with press in studs
- the 289 hi-po had a dual point dist as standard (and i think no vacuum advance either). 289's had single points (assuming that the dist hasn't been changed over)

also if it is a 2bbl carb, chances are unless someone changed the intake out, it is not a hi-po engine.

just a couple of more things to help you out.

Looks like I have a standard 289. Head casting # is 66, press in rocker studs, single point distributor. At least it does have a dual plane, high rise, Edelbrock manifold on it. Also, it is a 6 bolt bell housing.
Thanks for the help, Jeff

 

5 bolts: Before 8/23/1964 // 6 bolts: From 8/23/1964.

5 bolts: Aluminum waterpump // 6 bolts: Cast iron waterpump.

The timing cover is also specific.

Is the 5 bolt engine a 289 or not? It could also be a 221 or a 260.

 

Hey guys, question here. Did I decode this correctly. My casting number is C9DE 6015-B, if I'm correct isnt that a 69 Falcon engine and if it is is it the 2.8 or 3.3? Sorry if this is a stupid question but I plan on getting the normal tune-up stuff this weekend to get my baby fired up. Thanks...

 

Uhhhh... something is not right with this, my engine has a date casting of 4G29 (July 29 1964) and it is a 6 bolt bell housing and has an aluminum water pump. Do I just have something morphadite, which wouldn't be unusual for me, or a rare critter.

</TD></TR></TBODY></TABLE>I would never argue with the wisdom of Bill, but I will interject a couple of thoughts that may shed some light on the issue.

Bill is reading dates from the Ford Master Parts Catalog. One can perhaps safely assume they are speaking of the date those parts were supposed to be first used in production and assembly of the vehicles. Given that, it wouldn't be unusual for the new castings to be made at least a month or two prior to the day they were supposed to be installed, so there is sufficient supply. It's also possible that the 'best laid plans' didn't exactly work out perfectly and certain parts were intermixed until supplies ran out, and the new designs were then substituted. As far as I know, the timing covers will interchange on the blocks, but the water pump and timing covers are specific to each other, and must be a matched set.

 

You just cannot be sure when it comes to things that Ford did (and does!).

C4AZ6019B (replaced C2OZ6019C) .. Timing Cover / Use before Change L/#8.

C5AZ8501K (replaced C2OZ8501C) .. Aluminum Waterpump / Use before Change L/#8.
----------------------------------------------------------------------------------
D3OZ6019A (replaced C5OZ6019B) .. Timing Cover / Use from Change L/#8.

D3UZ8501A (replaced C5AZ8501E).. Cast Iron Waterpump / Use from Change L/#8.

Before Change L/#8, the blocks had 5 flywheel mounting holes. From Change L/#8, the blocks have 6 flywheel mounting holes.

According to the 1965/72 Ford Passenger Car Parts Catalog, Change L/#8 occured from 8/23/1964.

52 Merc: The timing covers will interchange on the blocks, since the timing cover gasket is D9AZ6020A (replaced C2OZ6020A) = Fits: 221/260/289/302, from 1962 thru 1989.

1990/96 is different (F0AZ6020A).

btw: Ford is in-famous for replacing (updating) 10's of 1000's of part numbers every year! Trying to keep track of all these part number changes was (and still is!) a royal PITA.

 

Thanks Bill, I know how it goes with part # changes, I have worked for a GM parts dealer before. Sometimes it seemed that the supercede book that came with the new parts book was the bigger of the two I loved it when I worked in parts for an International tractor dealer, if the part was assigned a number when it was first manufactured, that is still the number today, no matter how long ago it was first made.
