I wonder how many miles it would pay for itself in fuel mileage vs the old 8v? lets say fuel is $5.00/ gal an 8v92 gets an average of 7mpg and an 8.3 gets 10mpg. It would cost about .71 per mile /8v92 and the 8.3 is .50 per mile, thats a difference of .21 cents per mile fuel savings that would pay for itself in approximately 100,000 miles, not to mention the cost of parts, longevity and oil consumption. I understand some would rather have the original engine where the cost isnt an issue and like the nostalgic part of it, and some would like to have the more efficient newer engine. The trucking industry has proven this with countless miles and the inline 6 is the industry standard these days. If I had to choose between the 555 or any other older v8 4-stroke vs the detroit 2-stroke I would go with the 2-stroke detroit, but for me that is a past era.
