The easiest deal, may be to find a new Roadmaster or Jasper 6.9 and slap that into the truck. A NEW Roadmaster 6.9 is like 2500 bucks with a warranty.. Then you could spend a few bucks more and slap a turbo on it, and you could use all your good 7.3 stuff and have a really stout engine, and never have to worry about caviatation. Just an idea, since it is cheaper to buy the 6.9 and throw some ARP studs at it, and have a bulletproof IDI.. Anyhow, I live on Pendleton in San Onofre 1, so if you need any help, I can help you out. Good luck.. Scotty
