Question for Joe Lucia or anybody that knows about Oil Pan#360866

[Larry E.]

Restoring a 1966 base L-75 Coupe. It has the wrong oil pan installed on it now. Found and bought a
NOS #360866 Oil Pan which I understand is a service replacement for the original pan#3820000. Does
GM still sell the proper oil pump with the proper oil pickup installed? If not who does? Thanks in advance>
Larry P.S. I know all about the proper gasket> Will use Fel-Pro OS34510T

First of all, you have the right oil pan. The GM #360866 is virtually identical to the original GM #3820000 except for the front oil pan gasket radius. This difference is difficult to discern with the pan mounted on the engine.

As far as the oil pump goes, GM never offered an oil pump for a 1959 or later Corvette small block with a pre-attached oil pick-up. For one thing, the depth of the 63-74 and 1980-96 Corvette small block oil pans was different than other Chevrolet model small blocks. So, if Chevrolet had offered a pump with pick-up installed, it would have been unique to Corvette applications. As far as I know, none was ever offered for any other 1959+ Chevrolet small block application which would have been FAR more numerous.

Once-upon-a-time, there was an oil pump with pick-up assembly available for Chevrolet passenger cars and Corvettes which shared a similar oil pan sump. This was for 1955-58 models and was GM #3755420 It was discontinued without supersession in 1983.

I don't know of any other source for an oil pump with installed pick-up for 1963-74 or 1980-96 Corvette small blocks. In fact, I don't know of one for 1975-79 Corvettes which used a pan the same as many other Chevrolet small blocks.

Thanks for your input Joe: Now>Does GM offer the proper Oil Pump w/o the pickup installed? If not I guess I would have to
order the pump and pickup through Paragon or? I see they offer a "Standard Pump">#10366 and P/U #8614. Thoughts?? Larry

The correct pickup screen original #3830080 listed for Corvette 63 - 69 with 327/350 engine.

Yes, the current GM pump is GM #93427692. I believe this pump is manufactured by Melling but it's not the same as their standard M-55. I believe it's the same as their much higher quality Melling 10553.

The GM #3830080 pick-up screen is GM discontinued. You can use a Melling 55-S3 which is identical.

Re: Question for Joe Lucia or anybody that knows about Oil Pan#360866

Joe, I'm a bit confused. If replacing the 3822000 with the 360866, are any modifications required (other than the thicker seal)? I have a NOS 360866 & had a buyer interested until he was told that the oil pump required modifications.

Thanks,
Ron

Re: Question for Joe Lucia or anybody that knows about Oil Pan#360866

Ron,

The oil pump pickup screen needs to match the oil pan application. If the original pump and screen are Corvette they should work just fine in the new oil pan without modifications. If the pickup screen is not Corvette it will need to be changed to match the oil pan.

Absolutely no modifications are required to the oil pump or pick-up screen when replacing a GM #3820000 with a GM #360866. The pans are identical except for the front seal radius. I don't know who told the potential buyer that the oil pump needed to be modified but whoever did so did not know what he was talking about. Guaranteed. Period.

Joe,
Did GM make a gasket set for the #360866 oil pan.

Yes, they did. I believe the part number was GM #14079399 (I can't confirm that right now because I'm away from home) It's discontinued, though. Easily available from aftermarket sources. However, this is a 4 piece gasket set. I only recommend using a 1 piece gasket.

As a matter of fact, the 63-74 "5 quart" and "6 quart" oil pans can be interchanged on an engine without the need to modify or change the oil pump, oil pump pick-up screen, or even adjust the position of the pick-up screen. No need to change dipstick or dip stick tube, either.
