Is this a 340 or 360 pan? Need one for my 5.9.

Hi guys what do you think on this pan 340 or 360?

It looks like a 360 car pan. The rear seal is area is smaller & narrower than the front. If it were a 273/318/340 pan, the rear seal would be the same as the front.

If that's an OEM pan, there should be bold 3# stamp that would provide more details (year & model use) if someone knows the numbers.

Thanks a bunch Loco.
Thats what I thought but needed a second opinion.

 

[Locomotion]

Never hurts to double check.

I have a 360 pan that I believe is around the
73-75 years, and the number stamped into the oil pan is #392, but there maybe other numbers too.

Really easy. the 273/318/340 pans, the half moon cutouts are the same size, pretty much. The 360/5.2/5.9 have a smaller cutout in the rear

Get a 5 gallon bucket and 5 gallons of white vinegar, and then soak that thing in the vinegar to get the rust out of it. Cheap way to derust it.

The east way to tell a 360 pan is by the raised seam at the back of the pan as in ur 3rd pic. So u have a 360 pan. Kim
