Can't find an oil pan for Buick 231?

I have a Buick 231 in my 1974 CJ5. The motor had low oil pressure when I bought it so I pulled the pan to check the oil pickup. I noticed the pan had welds around it and the pickup had a circular weld around it too. Thought that was weird. The pickup was clogged after sitting for 15yrs. I pulled it and got a replacement and noticed the angle was different. Well the pan has the sump moved to the other side and I think they cut the old pickup and angled it to match the sump. I can't get the pan back on with the new pickup sitting in the shallow side of the pan. I cannot find a pan for this engine anywhere. Its a basic 14 bolt pan that seems common for the era but no one carries one. Got the only one I could find on ebay and he mislabeled it and it was for a v8 and had to be returned. I am stuck and my project is kind of at a stand still. With the numbers on the block I figured it came from a 1979 Buick Skylark. Any help or suggestions would be appreciated.

Would there be any problems with just taking a hammer and beating the pan out a little so the pick up fits? It is just a tad to short.

TA Performance Products still lists a chrome stock configuration 14-bolt Buick V6 oil pan on their website at http://www.taperformance.com/proddet...prod=TA_V1511A I was into Buick V6s quite heavily about 20 years ago and Kenne-Bell was the big supplier at that time. Unfortunately, the KB website doesn't seem to list any Buick V6 stuff currently.

Hope this Helps,

That Summit oil pan is for a SBC and won't fit a Buick V6. The Dorman oil pans listed on Summit's website for V6 applications are all for transverse FWD cars and won't work for a longitudinally mounted engine.

No problem. You really do want the correct matching oil pump pickup and pan/sump configuration to avoid any problems with the pickup becoming uncovered during cornering/braking. I don't know if the chrome oil pan will make your Jeep any faster, but it can't hurt.

No, that also looks like a SBC oil pan. It definitely won't work on a Buick V6.

It's funny, if you look at the first pictures it looks similar, then you look at the 2 pics below and it's a completely different pan.
