383 oil pump ?

Hello again,
was hoping someone would know what oil pump this is tried looking up the # but came up with nothing so I'm asking here.

Thanks
Rob

Standard big block oil pump. Looks like a sealed power number maybe.

Thanks for reply, but not what I was hoping to hear, thought maybe it was a high volume aftermarket oil pump
Thanks,

Rob

How thick is the body of the pump between the engine and the outer piece? High volume pumps are noticeably thicker then stock. Your picture doesn't show that part, In most cases a high volume pump isn't necessary. Why do you think you need it?

What do you think now? Stock EH!

Thanks
Rob

It looks thicker than stock but I'm not certain. You might want to post this in the race section. Those guys are really good at this.

HV pump, the newer HV pumps come with a high pressure spring, you have a stock type pump.

If you're running a stock oil pan and your oil clearances aren't on the loose side, then a stock type pump is what you want.

Thanks for your reply's
the 383 hp motor I picked up came with this oil pan and windage tray plus the aftermarket carter performance fuel pump so I thought maybe the oil pump was hv?Is there a way to tell by taking it off?

Standard pump would be fine for that set up. No need to take it off. You can tell by the difference in measurements that you have a standard pump.

The thickness of the pump body is how you tell if it's a high volume pump or not. Your pump appears to be about 1/4" shorter than the HV pump pictured above, so yours would be a standard volume pump.
Like I said, not a bad thing and it's likely all it needs.

Awesome thanks for your reply's!! always learning!!!

also the picture of that engine, there is not a windage tray installed

And it does not look like a new pan.

Good eye! yes I know because I removed the oil pan to restore it check it out!

Stock "nothin' fancy" replacement pan - not even a larger capacity "hemi" pan. The last guy just cheaped out, don't expect to find any bonuses in this motor.

971 came with baffles front and rear, 5 quarts plus filter nominal fill, to my way of thinking that's actually not a
horribly bad street performance kind of a piece.

The pump just looks like a stock piece but that's okay, if this is a stock-ish kind of a build I'd add a windage tray
and that's about it,

Thanks ZIPPY That's what I thought about the pan a little better then stock so I restored it.Not building a race car just a nice cruiser...

cheers

As far as oil pumps,I've had this one a "long" time,ask before and never got a legitimate an answer.New in Chrysler box,I'd have to look but if I remember correctly,part number starts at 25 something,never could find any reference to the number. The M63 on the pump is also on the box

Melling pump. https://www.ebay.com/itm/Big-Block-...lume-Oil-Pump-Melling-M-63/202622900939?

Cool car.

Still wondering about the slot,been fooling with this stuff since the 60's,first one I ever had or have seen.

the title states a standard volume pump, but in the description states the part number as M63 HV, which i would ASSume denotes a high volume pump ?
