I was going through your headers and want to know what header will work and this truck? It a 1973 3/4 wagonmaster 4x4. What are my options if any or not for this s 392.
For your 73 fullsize, you can use the Scout II headers as your engine mounts should be at the transmission bellhousing and below the front timing cover. We usually recommend the tri-y style as they produce more torque than the standard four into one collector. Thanks.
