So it seems i'll be doing the oil pan on my 351w as it started to leak recently. While i do that i'll be replacing the oil pump, and pan. Oil pump as there is no better time to do it, not that it has problems. Anyway my exhaust is totally rotted away and i'm thinking of getting headers, and in the future getting a cam. So what cam would work with the sd efi system? Any recommendations for headers? This truck is / will be used for daily driving, plowing, and towing in the future.
