It's my understanding that all magnums use a 360 oil pan, which I have, but I need to use a pre-magnum 360 oil pan gasket set. Is that correct? Also, I'm putting a pre-magnum 318 crank into this engine, do I need a magnum or pre-magnum rear main seal? Thanks!

The Magnum pistons and rods are lighter weight than the LA versions. You can use the one piece Magnum oil pan gasket if you make a wood or aluminum shims to glue in and fill the gaps at the top. Or hammer them out of the pan as said above. Scott B. "I'm a self-made man...

Safer to fab 4 small shims if you want to run the 1 piece gasket. Scott B. "I'm a self-made man...

It has the LA timing cover and oil pan using the magnum rear seal and LA oil pan gasket. The magnum gasket was gushing oil at the inside corners as said above. 76' Volare, 5.9 magnum w/Iron heads. New best 10.68 at 123 mph 1/4 mile.

I have never had a leak on my builds and I'm curious to know where the problem was. Are the inside corners the area where the timing cover and block and pan come together? I use silicone at all corners and have not had a problem. Last edited by StrkrDart69; 02/21/11 09:42 AM.

I can not believe that 318 Magnums use the 360 pan... They do, when Chrysler designed the Magnums, the commonized the pans. They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

That area just poured oil out when the engine got tilted pulling and putting it in the truck bed. I had put the magnum gasket in originally and run it on an engine stand. It did not seem to leak on the the stand. But we didn't get the balance right pulling it off with the cherry picker and oil just poured out.
