Default 12v vs 24v

Hey all, I want to get into diesel truck pulling possibly in the future, I have owned and been a cummins fan forever, but was wondering what everyones opinion is on what motor is better to build for pulling.
And also on the 12 valves, what era is better to build up, the early 90's or like the 95-98?
all replys are appriciated!
Thanks

Really if it was me ,

01 24v block , 05 24 v cylinder head then P/pump it then make lots of love the the head and block . Then use a large single such as a 2.8 or 3.0 charger. But you have to check with your local rules on turbo and what class you want to run .

The class dictates what charger.

I'm with MAX on this one, the 24v head flows increadibly well, and you just can't beat the fueling of the P-pump

I believe you have to change the ECU.

The Ecu is still there...it controls the oil pressure sender, voltage regulator and stuff like that just not fueling because the P-pump is gear driven. I think you can use the driver in the ECU to control the lift pump feeding the P-pump as well since that circuit is already there. But I might be totally wrong to LOL.
