I’m rebuilding a Dodge 340 engine for street performance applications. How do I know if I need a high volume oil pump?

A stock volume oil pump is perfectly adequate for most street performance engines turning less than 6,000 rpm with stock, or near-stock bearing clearances.

If you’re using remote oil filters, a remote oil cooler, bearing clearances for high-rpm operation, or any combination of these, you should consider using a high-volume oil pump. Check out Melling’s stock volume and high volume oil pumps.
