An Edelbrock Performer and an Edelbrock 650 AFB with some headers. Either recurve your present distributor, or get a Mopar HP ignition kit with an HP distributor. Have the heads worked with a fresh valve job and have the bowls blended. Add this cam and it should get the job done. I agree with the above there's no way in hell you'll get an honest 300HP with just a 4 barrel. Ain't happenin. With the above recipe, you will surpass 300HP.
