Mod For Mod Horsepower Diesel 7.3L vs. 5.9L (24 Valve)

Ok First Off Let Me Start Off Saying that I don't want to start a war here, I'm only trying to find out some feedback/opinions on such motors.

Feedback/opinions are greatly appreciated.

Here are some stock specs on each motor:

1999 7.3L PSTROKE 235@2,700 500@1,600
2001 7.3L PSTROKE 250@2,600 525@1,600

98-00 5.9L Cummins(24v) Auto 215@2700
420@1600
98-02 5.9L Cummins(24v)Manual 235@2700
460@1600

Stock for Stock the Powerstroke has a slight heads up, but once the mods start which gains more Horsepower/Torque?

Yep the cummins.....I believe it has to do with the fact that you can tweak the fuel so much more because of the common rail on the cummins

No CR until 03... but the main reason is the fuel injecton process on the cummins lends itself to mods better.

The whole design of the motor lends it's self to better reliability and power. Inline, bigger parts, less moving parts, basic... all of the above = big power with little changes.

Cummins baby!!! Beefier pats, pumps with nearly infinate power potential it seems, all in all a very basic platform (12 valves...kinda the CRs also but more electronics) with tons to work with
