Anyone know about 1990 Cummins?

I found this awsome deal... DODGE CUMMINS
and was toying with the idea of getting it for the engine to go in a SuperDuty (possibly my dually, possibly a single cab short box

)
But I don't know what year model is best...i know there were a few years that were better than others for the Cummins.
Anyone?

Im not sure but I know the 90 cummins will be a massive turd. They have no balls at all, which my be easy to change but will take alittle more than say a 96 cummins. IIRC the 90 model year was rated at 160 hp at the flywheel.

The 97 is the motor you want if your doing a 12v. I found a 95 the other day for $2000 that was a daily driver with a 5 speed.

Really...hmmm

How about this smokin hot deal

Assuming the seller is telling the truth about the miles and the fact that it runs, this would be hard to pass up

I would snatch that up if your wanting to do the swap. The 12v is my choice but the 24v can make some power with the right tunes.

not entirely positive but i think this is a gen 1 and as far as the 12v goes gen 2 is more desirable (all based on the injection pump vpump vs p pump

Yes you are correct! The 90 model will not be p pumped and will not make the power he is wanting.

A 90 cummins is a VE pumped cummins. Basically it has a rotary VE pump on it. They get the best fuel milage out of the cummins. The pump gives them a really good torque curve. These are the motors that will put out some crazy torque numbers, like 400hp and 900ft lbs of torque. I actually perfer the VE pump as it has a better advance curve than the P pump cummins. Great motors, and there are lots of mods for them. They dont have cam plates like a P pump does, so getting lots of power out of them requires a special pump head, I think its called something like 14mm head or something I forget. Dont shy away from them, they are great.
