427 fe dry sump oil pan !!!!!

[jerico427]

Hi guys check this out i think its a dry sump oil pan for a cobra or any FE
Anyone know for sure ????? THANKS !!!!!!

It looks like it, that may be a rare piece in cast ally.

[jerico427]

And it has never been bolted on
I guess it could be nos?

Not so much dry sump as external pump pan.

I have one of those myself, even did bolt it on (had to fiddle with the front rail a bit), but in the end I didn't want all the plumbing and belt problems that come with externally routing oil.

Happy to see a pan that I'm looking for. If it is for sale let me know.

It is a dry sump pan.
Not enough capacity to be an external wet sump.
I like the extra cast in pump bolt boss on the pass side

I was told it was a pan for an external pump, Marine application specifically.

If you've ever seen one of those massive HM double-filter water cooled remote oil filter mounts, you wouldn't worry about oil quantity in the system. Since mine was used, from the original owner, I'm going to go with his ideas on what it was for.

Looks more like a dry sump pan meant for a multi stage (3-5 stage) external oil pump.

That sump would suffer from oil surge and so a single stage external pressure pump would be starving for oil, and oil pressure loss to the engine is the result.

Two scavenge pumps ( 2 stages of a 3 stage pump) sending the oil from the pan to a remote dry sump tank that the pressure stage can draw from will supply a surge free oil supply to the engine.

Belt driven Dry Sump Pump which only had two scavenge sections bolted to the lug cast on the pan exterior between f/r scavenge points. Original oil pump still fitted as per normal to supply pressure side of system inlet for it was round hole in triangle shaped pad. Remember seeing pics of this in an early sixties mag about dry sumps-there were two setups, one had shelby links ,but cannot remember the other.

This doesn't make sense. Where is the scavenged oil going and what are we doing with it?

Normally, the scavenged oil goes to a swirlpot collection tank and the engine pressure pump draws from that tank.

Would not be a match to CSX3020, I think that used as LeMans GT type so it was different. CSX3002 was similar but in steel.

Only because your thought process is clouded by the image of modern practice, the scavenged oil goes to the swirlpot/external tank, from the bottom of that tank via a line back thru that 'hole in the triangular pad' & onto the pickup tube of the original internal pressure pump of the engine, system is then on thru the pressure system as per normal.
Does not get rid of any of todays associated problems like oil pump drive-dizzy gears etc, but then when you think about it with a nice continous supply of de-aerated oil from the tank life might have been easier on the pump drive, and maybe the oils were slightly better back then along with real mechanics rather than just the parts fitters of today.

Thanks for explaining Jac.

I understand the concept, but I don't understand why anybody would go to the trouble of dry sumping, fitting a multistage external oil pump for scavenge use only, and then rely on an internal oil pump for supply.
The one and only advantage I see is if the external pump has a mechanical failure or the belt comes off etc, the engine will still have oil pressure in the time it takes to shut it down.

Just look at the modern Vette Z06's, same style setup...

Which is probably why my boat guy was using it. Plenty of room in a boat for tanks and (untangled) oil lines etc...

Look about half way down and you will see a complete dry sump system with your pan.
