I just melted my 03 6.0L with 78,000 miles on the odometer and refuse to replace it.  I did everything I could to make it last (four months past warranty experation).  Go ahead, laugh now. I want a Cummins, but can't decide which one.  I heard the 12V installs easier.  I might have a 2000 doner. Any suggestions?  

Isn't the '00 model 24v? 12-valves are pretty straightforward. Either one is OK. I heard the early 24v models had some injector pump issues, but the later ones should be OK.  

the p-pumped 12vers are prolly the easiest to transplant due to least amount of wiring the 12 valve also has 3 holes on the block so it leaves more room for adjustability forward or back for motormounts. i dont think you will be disapointed if you do it.  

no matter what somebody like you does to a vehicle it never stops amazing me!!! you probably have every aftermarket kit known to god on it,please change over to dodge and see what junk really is!!!!!!
