You're almost better off staying with a B2600i, as the V6 MPV & the 2.6L share about the same horsepower. I own a 1992 4WD MPV 3.0L V6 and this is the most gutless POS i have ever owned (on road). When I am offroad, then it is one of the best 4x4's I have ever owned. I can and do go places that Quads go (they hate me)...
If I was going to do an engine swap of a B series truck, I would go with the Cadillac Northstar V8, the smallest V8 made @ 300hp.
