Conanski. Please give me engine build details

Considering you can get that for literally a few hundred dollars in parts it's hardly worth the effort to swap in an IDI IMO.

Hey Conanski, could you tell me the details of you cam and headers on your 5.8L , I have a '93 f250 4x4 F250 with a 351 and 5spd and would love to get that kind of milage
thanks mat
