also a better cam to match the heads port and polish. also different headers to match the air flo that is going threw the engine. i know if a engine breaths better and runs cool it will have a gain. i wonder if the heads mention a acid dip for the oil gernals and the water gernals. to help as well for the performance but some web sites that do more for one type will do some for anouther but not much. as in being limited do to the unpopular engine pakedge. i know the 3.5 is not a popular one but i am wondering if there is a site going to be dedicated for it. but with the 3400 i would go to 60degrees as well for some of there stuff for the 3400 like the heads and the pakeges for the 3400. also check milsy for a retune if possible

 

I believe he means Ben from WOT-Tech.

Yea bumpin, im kinda thinkin the same thing..although you can shoot him an e-mail asking hime, idk if he'll know but im sure he could give you some numbers, but then again he might try to steer you into a turbo kit for "some serious hp numbers" as he did to me asking about the PCM upgrade lol.

Anyways, how far could you go before rebuilding the bottom end on a 3400? I know that you can go pretty far with the 3800 stock bottom end, but would it be the same for the 3400?

In the near future, i plan on getting Milzy's PCM tune, and making my own Cold Air Intake, and maybe, just maybe slapping some duals on that baby. Even though I know that no where near to having to rebuild the bottom end lol but just curious.
