3.3 is weak
After losing my 3.8 to a random oil dump, I swapped a good/low mileage 3.3 in it's place.
I did some porting/cleanup, which to my surprise, there isn't much for flaws in the 3.3's heads to clean up. I also added my 58MM tb, spacer, shorty intake, and bigger exhaust.
It runs great and feels strong, but it's severely lacking in the low end. After having the 3.8L for so long, I'm having a very hard time being happy with this new setup.
So the question is, what can I do with the 3.3L to make it perform better?
94 Voyager: 3.3L/4-speed swapped, Off-Road Mini
95 Acclaim: Mild 3.0/a604 swapped, originally 2.5/3-speed.
92 Caravan: Stock 3.0/3-spd, 69k orig mi.
