3.9 Liter V6 Swap

I think the question of mileage between a 4000lbs + truck and a 2700lbs car will be different. Especially if it's a 4wd Dak. If i couldnt get 25+ out of a magnum V6 (injected) with the OD trans in an early A I'd figure out what wasn't working right.

The 225 has a small carb, small ports, and 3/4" more stroke. It will respond quicker and it's advertised power peaks are (HP)800 rpm & (TQ)1600rpm lower than the 3.9's. But - the 3.9's still 65hp and 40 pound feet higher than the 225. It might feel quicker because of a faster pedal response - but in the same weight and geared package - it's not.
