lets talk pan gaskets and rear main seals

I did this on my latest 340 build. Cut the Magnum pan rails from a late model one piece Magnum gasket (rubbber with steel insert). Used the stock 340 rubber pan gasket ends. RTV'd the corners. This was a recommendation from Brian Halflinger at IMM engines. The steel core prevents the over tightening of a cork or solid rubber and distorting it. :glasses7:
