First off, the "new" 3.8 isn't OHC. It's pushrod, just like the 94-98. In fact, the block is the same (with a few small changes in the casting to strengthen the block). Secondly, the extra hp comes from better flowing heads and intake.

Oh from what i understood, the 99 3.8 only had the same bottom end as the 98 ... so technically if I had better flowing heads and intake my car would technically gain 50 hp?
Im curious.... I just never knew, I know one is a modular and the other is pushrod, but what did they change?
there are no modular v6's
the split port head configuration and intake manifold changes add up to a lot more air getting to the cylinders, along with a cleaner burn.

yes.
but the 94-98's have more flow potential.

If thats the case it is not a 3.8 but a 4.0 V6 SOHC, and what they changed? well everything, it is a completely different engine.
The one scheduled for 2005 has 15 more hp, and lower torque numbers.
THe 2006 or 2007 3.5L should have 250 hp.

Oh so if I were to say port and polish my intake and heads i would have more than 50 hp like 70+?
I don't know if the cam has changed from the 99- models . . .
But if the cam is unchanged, then yes, you could probably get that kind of hp from a 5 angle port and polish.

holy ****, sounds like a nice deal prolly costs like 1000 though :\
If you find a local speed shop, a three angle port job shouldn't be that expensive, if you remove the heads.

The 99+ V6's actually have less cam duration than the 94-98's.
Really?!
I guess that accounts for the better MPG numbers.
