72 350 correct oil pan?
Replacing a leaky gasket. Before I reinstall I am wondering if this is the correct pan for a base 72 350. Thanks in advance.

I recently did this on my '72 L48 350 base. If you are going to use a felpro 1 piece you should get this part number OS 34509 T.
When I did this I also replaced my oil pump because I read it is always a good idea to replace it when doing this. I bought the standard Melling pump, the high volume rod that turns the pump (since the high volume has a metal retaining ring welded to the rod), and a pick up tube. When I removed the oil pan I realized the stock oil pump pick up tube is not like most you pick up after market.
If you can find a stock design replacement pickup tube, that is best. If you figure out a way to remove the original pick up tube you will need to weld it to the pump because it is impossible to press it in adequately if it is reused. It's a bit tough to weld as well because the pick up tube and pump are dissimilar metals.
...Just a forewarning.

Its interesting that you bring that up.. With respect to the gasket. I thought that I needed the thin gasket. When I measure my distance at the front of the pan I got 2-5/16, right in between 2-1/4 and 2-3/8. As I looked closely at my pan I noticed that it doesn't sit flat due to the fact that each bolt hole is a bit flared, which rises it up what I think is that 16th of an inch.. If totally flat I would think I'd be at 2-1/4 which is supposed to be the thin gasket according to several sources around the internet.. So I was going to get the thin one. Not true?

Yes it is.......I used the stock pan on my 406 when I built it as it was in excellent shape.............great oil pan.........lots of sump area and mine had a trap door in it
Not all had this trap door though........but for discussion, your pan looks exactly like mine.Jebby
