Why? Look at the weight difference. I can't see a significant advantage over a small-block v-8 with the 4BTs (except fuel economy), and the 6s weigh over a thousand pounds! A healthy 351 or 350 will still weigh half of one of the 6s. Although getting the 500 ft/lbs would a significant chore, 400+ ponies is not that hard to accomplish with aftermarket heads, and there would still be a larger rpm band.

Plus, no one wants to be behind a diesel on the trail ;D .
