Will 72 340 oil pan work on 73 360?

OK well I came to relize that the rear gasket for the 340 is bigger and 360 is a smaller rear gasket. But But that seems to be the only problem so we just put the 360 front gasket on the rear to fill top gaps the on the 340 oil pan. It seemed to work but I was wondering should I be afraid of leaking from the rear?

I would use the correct oil pan.

We had this problem too. I would highly recomend getting the right Oil pan. The way you have the seals will only lead to further problems. You might have to buy one out of summit, but its worth it. When we bought one, it was around $100.

What?  The 360 has larger mains, and therefore, a larger radius around the crank in front and back.

The rear seal is smaller on the 360s.
