Randy, when do u plan to install the pump ???

WIll someone else try to access the 55-56 Xref at the AACA Packard DF. Click on the 2nd pinned topic then click on the 55-56 xref link there. Won't let me get to it.

The pump you looked at at NAPA was probably a Sealed Power pump. It's the same thing, just a different manufacturer. I'd bet it would fit. As long as you go order a pump for a 455 Oldsmobile, you'll get the correct pump. It's too bad that Kevin's x-ref doesn't include the option to add pictures, as I'd post the part numbers and a pic of the oil pump for the conversion. This is the pump that everyone should be getting:


----------------------------------------------------------LINK----> High Volume Oldsmobile pump

This is the Melling oil pump, any oil pump that fits an Oldsmobile engine will work, just try to get the high volume version, it'll help out with such a big engine, even if it's a "little" Packard 320.

I also have a nos chrome valve cover with red script that is still in the box.

Anyone know someone who owns or has a good relation with a Napa store? When I was going to order the Melling 22FHV, they had a crossover number and different mfg for that application. Since it was different, no pictures, and the instructions on conversion and pan clearance were specific, didn't take a chance because of the special order and restocking fee. Maybe that would be worth checking out because of the multitude of Napa stores around. In addition to calling it the Olds conversion, also pick a base model and year as a starting point for prominent display in the x reference.

Regarding the question of "automotive application", when I ordered this kit back in September 2006, I was merely told that:

Quote:
I cannot recall the model year range shown in the Melling catalog at the local parts store, but they did offer both standard and high-volume versions of the Olds V8 oil pump. (BTW, the numbers I posted previously were quoted straight from the Melling cartons.)

The only thing the GM parts books show for the Olds V8 is the stock oil pump, which is DISCONTINUED. While I did find a listing a for high-volume pump (P/N 22532198) for the Olds V8 (all 307-455) in a 1998 edition of the GM Performance Parts catalog, it is also DISCONTINUED, and I have no way to tell who made it for them.

Do other suppliers still offer a high-volume pump for the Olds V8? Is so, how about providing some alternate numbers and feedback on their use.

Correct, but It's still called the "Olds oil pump conversion". Calling it the "Melling oil pump conversion" is a little ambiguous.

Summit racing lists the 22FHV for a wide range of Oldsmobile engine & model combinations from 1964-1990.
