What's the difference between 95,96,97 7.3s

Diesel newb here. I'm looking to buy a 7.3 OBS and I'm not sure if there are any major differences between the 95, 96, and the 97 motors.

Also, would you buy a 95 XLT Dually? If not, why.

Any help would be greatly appreciated!

Essentially, there are only minor changes as far as engines go, power outputs changed sightly as a result of different tuning.

The 94.5-early 95 used a High pressure oil pump that is different from later models. Using a later model pump will result in the High pressure pump supply reservoir draining out when parked. There are modified pumps and other modifications that will work around this issue.

The mid-95 and 96 engines were pretty much run-of-the-mill with no noticeable changes.

96 and 97 California models used a different PCM and wiring, utilized split-shot (pilot injection) injectors, and had a pulsation damper on the fuel pump.

1997 engines had a different oil pan, oil pickup, and front cover in an effort to reduce the "dry start" of a lack of lubrication oil being pumped. The 1997 block was also thickened and reinforced internally in an effort to reduce combustion noise.

I don't know about the 97's being quiter. I have a 97' and whenever I see another OBS, I try to compare the noise to mine. Mine always seems to be louder even though I still have the Cat and Muffler. (Soon to be removed.) I like the sound though. I just put in a high pressure crossover oil line and it seemed to smooth it out a bit. I have only had the truck for about 4 months, but love it!
