hey guys!!
so shortly i will pull my 4.9 out to rebuild it since i'm blue smoking. Its in an 86 f150 4x4. I've already put an offenhauser intake with a holly 390 cfm and headman headers on the truck (someone got leadfoot after this and ran the truck a little hard ) With the engine build i want to get the most power possible and keep duribility in mind. At this point for upgrades i'm looking at a cam, roller rockers, and 240 heads. any more recommendations to get more power out of this engine?
