I have a new MP high volume big block oil pump, part number P4286590, installed on my yet to be run engine. The engine is a 400/470 stroker and I was planning on using a factory 187 notched oil pan as it is going into my Dart. I was just reading an article that said when using a high volume oil pump that a 7 quart pan should.be used. Is this true? If it is, will a standard volume oil pump be sufficient for this engine or will I need to go with a higher capacity oil pan?

I had to correct this. I have a 187 oil pan, not an 893.
