Dollar wise and milage wise alone the 4200 is a good deal even if the power was the same but it's not. They just make me feel the way I did when the Lotus Fords took over the Indy 500. They just don't look or sound right. Here is a link to a friends Chevy pickup with a 4200. It was in progress. He modified the frame to take the stock pan.
