Ive been pondering a v6 for lightweight project and being a mopar guy I keep coming back to the 3.9.
But in my experience the 3.9's even new were gutless and not great on fuel. I've even seen more blown up 3.9's than 5.2 and 5.9 together.
But why? Is't the 3.9 just based on a magnum 5.2? Are the heads comparable flow?
What is it that made them so disappointing compared to a gm 4.3 or 3800?
And how hard is it to make a 3.9 better?
