: After going thru some old Chrysler manuals,I am finding that stamped and cast oil pans were both used in marine applications.Is this determined by the position of the oil pump sump? I have a 360 that I am trying to finish,I have a stamped pan that came with it,but my 318 had a cast pan. In the 318 application the bell housing had two adjuster type bolts that were connected to the oil pan,are these inportant? My 360 crank has a groove in the rear of the crank where the oil pan seals to the pan. The 318 crank was smooth.The seal on the 318 oil pan is set up for this smooth type crank. What oil pan should I use?? The 360 cast pan is 540.00!!!! Do I need this pan and if so, will it seal to the groove in my 360 crank??? or is there a special seal kit that you add to it to make it work??? HELP,I CAN'T SEEM TO GET A STRAIGHT ANSWER FROM CHRYSLER MARYSVILLE ABOUT THIS ISSUE.

The 318 pan will not work on the 360 because the rear crank cap is different. The 318 pan will bolt to the 360, the pan rails and the front seal will match, but the rear main will not. The 318 has a larger radius than the 360 and uses a different rubber seal. The 318 has a groove in the pan with a smooth cap and the 360 has a groove in the cap and a slight lip on the pan to press the seal into the cap.When I converted from a 318 to a 360 I bought the cast aluminium pan ($340.00 in 1993)and it was hard to find one at that time. I also had a 318 cast pan machined to fit a 360. The machinist cut the pan then formed the new radius in aluminiun and welded it in place($175.00). He did a great job and it worked fine.I used the cast pan because it had a higher oil capacity than the stamped one that I had. What ever one you use make sure you use the correct pick up for it.
