Yes I picked up that they had great reliability and endurance from an old add someone posted to me; "Our first V6 went 246,000 miles before it's first service". That's sure attractive - but for the milage thing. With the right carb, largest wheels possible and a different differential perhaps 12-14 mpg possible. It's an impressive engine. I wonder as the literature repeats over and over that the 305 and the 351 are almost identical - does that mean the 305 has the density of steel the 351 has?
