    water pump pulley

    Ed, the COAE9425B tells you that the C0=1960. The 9425 tells you that it is the intake manifold and the B is the revision number. As I recall, the OD11 is the manufacture date. Someone like Dave, or jopizz can break it down better for you.

      Intake manifold must be original if date is 1960. I was told the engine was from a mid 60's 390. If that is true, sounds like there is a mix of parts from 2 engines.

        Check and see if you have the engine identification tag. It should be attached to the driver side at the front where the coil originally mounted. I imagine you had to remove the coil to mount the compressor.

          If you can't find the tag look at the heads between the middle spark plugs. There should be a part number prefix there.

            Unfortunately, no tag at that location. Don't know if it was there prior to A/C install. Will ask mechanic, possible he removed it. Thanks

                Those are 1960 352 heads. It appears that you have the original 352 engine, not a later 390. I don't know if you can use 352 heads with a 390 block. Do have a generator or an alternator? Later 390 blocks had a hole to mount an alternator. Early 352 blocks did not.

                  I have an alternator. That being the case, the block would have to be a 390. Previous owner would have no reason to tell me otherwise.

                    I went thru some of this when putting a Sanden compressor on my wife's '60. Getting stuck between vendors recommendations and a motor that doesn't fit an expected standard. I can't help you with part numbers, or if original Ford parts are wanted, but I remember just walking thru a junk yard and taking a water pump pulley off something that had a wider 'bell' than mine. I think it was a Mopar. It had two sheaves so I cut one off (with a sabre saw). I aligned the belt to the compressor, measured the interior gap with clay, and cut down a fan spacer to fill it. Longer studs holds it all together. Been together 15 yrs. The fan's electric. Just sayin' you might get unstuck by getting off the parts lists and just using what works in your situation. Unless you want original.

                      They could have put in a "short block" and used the original engine intake manifold and heads from the old engine... If you look on the front of the engine, near the oil dipstick you will find the engine assembly date.

                        The plate has no numbers on it but may have been painted and numbers are under paint. Would the numbers be etched into the metal?

                          If you're not sure which engine you have, simply measure the stroke. There is 1/4" difference between a 352 and a 390. - Dave

                            To amplify what Dave said, read this...

                            Here is your firing order. 1 5 4 2 6 3 7 8, thanks to Dave. Here is how he explained it to me.

                            TDC-----BDC
                            1----5----4-----2
                            |----| ----|-----|
                            6----3----7-----8
                            TDC-----BDC

                            Here's the easy way to check the stroke without removing the valve cover. Get a straight 12 inch piece of white electrical house wire or coat hanger wire. Get a magic marker. Remove the #1 spark plug. With #1 at Top Dead Center (TDC) put the wire in the #1 spark plug hole with the wire resting on the top of the piston. Make sure the engine is at TDC in the #1 spark plug hole. Once you are sure it is at TDC, continue. Make a mark on the wire even with the lip. If you have not already done so, remove spark plug #4. Stick that wire into #4 spark plug hole until the wire is at its lowest point, Bottom Dead Center (BDC). Mark the wire again, at the lip, and check the markings. Here are the specs: 3.78" is the stroke for the 390, and 3.5" is the stroke for the 352 engine.

                            In other words, if I have this right, if the marks are at 3.78" that would indicate that it is a 390, and if the marks are at 3.5" (about 1/4" shorter) that indicates it is a 352 engine...

                              Ray, it's easier than that... When #1 piston is up, #4 is down.

                              Put your timing mark on TDC and don't move the crank. Stick the rod down #1 spark plug hole and mark it. Pull #4 plug and stick the rod down the hole and mark it.

                              Measure between your marks. The 352 stroke measures 3-1/2" between your marks. The 390/427 crank measures just over 3-3/4". So, if you measure more than 3.5" stroke, it's a 390.
