High Volume Oil Pump on stock 318

my5thmopar said

I filtered through all the suggestions and appreciate the responses. I left a message at Melling and actually got a call back promptly. Here is what I gathered from a call from an engineer at Melling. There really isn’t any benefit to using the HV pump in my rebuilt stock engine. A hardened shaft is not needed in a stock engine. He did say if I choose to use HV, I should stay away from heavy weight oils. He never heard of a Dodge sbc suck a pan dry. He said a stock pump is preferred in the 318 but, if I didn’t want to buy one use the HV pump. I don't think I'm taking a chance, if a stock pump works in every other 318, I'm buying a new one. Thanks

Good decision. I'd use a stock pump too. I've seen many engines go 300,000 miles with a stock volume pump so it must be adequate. And as for sucking a pan dry, I don't believe it's possible either. I think a lot of guys mistake sucking the pan dry with what happens under hard acceleration and the pickup becomes uncovered.
