FE Oil Filter Adapter

[wideglidejoe]

OK, I use a lot of books for reference mat'l (and now forums!), and I read that the C0AZ-6881-A is the BEST flowing oil filter adapter. I find a NOS C0AZ-6881-A on ebay and buy it. It arrives today; the box is labelled C0AZ-6881-A, but the actual part is clearly marked C8AE-6881-A. The C8AE ports look better than a stock FE oil adapter, but is it as good as a C0AZ?? Did I get took?

thanks in advance for your replies and sharing your knowledge!!

you are comparing a part number to an engineering number. the COAZ-A part may have the C8AE engineering number depending on the supercession of the numbers by ford from 1960(COAZ) to 1968(C8AE ).
parts do not have a part number on them it is an engineering number there is a translation catalog to get a part number from a engineering number. i would not sweat this at all use the part. the oiling mods you do to the block at the oil filter location will give you more, than worrying about a few thousanths of an inch of material in the housing.

FWB, thank you! I didn't realize the diff in part # vs. engr'g #. Ports do look good, so I'll plan on using it. And, I've made all of the mods to the oiling system on the block; main bearing saddle holes to line up with bearing hole, block to filter adapter, etc.

thanks again,
Joe

Did you open the hole up the hole in the block between the pump and adapter? That's an easy one to do.
