One piece oil pan gasket for small block - 01/27/22 07:59 PM

Does anyone out there know where that I can get one of these. It is an early 360 engine.
Jegs have the part number but they are out of stock.. 555-210495
Any help would be appreciated.

Thanks................Ted

I just picked up 2 of them from O'Rielly's last week, $42 Fel-Pro you can order them from Rock Auto and they are only $23

1993 Dodge Dakota with V8, doesn't matter which one 318 or 360, both are Magnums and use the same pan gasket.

Hmm...interesting...because as long as I remember, the one-piece gasket for the non-Magnum setups was basically made from "unobtanium"!!!

I looked at the JEGS item, and sure enough it says this will work with non-Magnum engines...but can anyone actually confirm this?

@DusTed74 I have a previously bought SCE gasket here, part# 269091, and I thought this would for my '76 360...it would not. If you are looking for that fit let me know.

Do a search here on Moparts and google for One Piece 360 gasket. But talked about before.

I got a the SCE one and it does not work on a LA 360 by itself. The ends are all wrong.

Magnums have a groove on the rear main cap, the LA 360 is flat, I think. I made mine for the 340

So you machined that groove in there?

I thought there was something about the corners of the cap to the block meeting area. Like you had to add angle wedges to make up for difference?

Nope, just not a true circle more of an arch. Oil pipe Straight down from the pump (well a little curve) and bigger diameter. Copied a magnum cap.
