rebuild the bottom end, i hear the rods try to leave at that power level . and i would think upgrade the cam and valve springs, pushrods etc. anything that has to do with the engine spinning, and fueling

 

Exactly what Turbo stang mentioned, There is nothing wrong with the LBZ, I recommend it highly, its what I drive and I love it, infact I just ran a 475rwhp tune for a few days and the truck took it like a champ, I detuned it simply because I like the truck too much to abuse it when I cant afford to be rebuilding the trans and Engine

Once the Dmax is built it can make some NASTY power, just look up Dimitri Millard, I think his LB7 just made 1500hp with a large volume of N2O

 

oh k thanks. the only thing i wouldnt do is nos to many dangers.before i would get to those numbers on the first engine would it be best to automaticly put head studs in. an if i do can i take them off the engine an put them on the other engine im building for high power.

britewhiteram what did u do on your truck to get that power an, in the latest diesel world mag they started a build on one of the dmax engines, an made 437 with out transmission work.

 

All i used was a tune, I cant say for sure that it was 475hp exactly but im ballparking because it came from Nick at Duramaxtuner.com and if he says the tune is 475hp I believe it, the reason im saying that it might not have been 475 for my truck is that the fuel rails were probably drained because i dont have a lift pump to keep the CP3 fueled

if you plan to buy a truck, but dont plan to build the engine right away, studs are not needed, the stock headbolts and gaskets can take quite a bit before they go

 

oh k what kinda lift pump u plan on getting for yours

 

FASS or AirDog 2 work well, just comes down to what you want to buy, research them and pick the one you like

 

oh k thanks, all this info will help me out a lot when i get home an buy me a dmax.
