$ and time frame. Traded a buddy for his 6.9 that has better oil pressure then my 7.3. 7.3 idles at 7psi hot. I possibly have a line on a p-pumped 12v later this year. But then have to buy a adapter, engine mounts, clutch/fly wheel, other odds and ends. So it'll take a little time before I have every thing for a repower and keep the wife happy at the same time.
