1970 LS-5 Big Block

In reviewing a road test article for the 1970 Corvette, 454 LS-5 big block engine I was struck by the notes on the mpg’s of the car (7-8 mpg). Now with a fuel tank of usable capacity of say, 14 gallons that adds up to a ridiculously short cruising range–anywhere from 98-112 miles per tank. Now, these cars were built at a time when fuel was plentiful and relatively cheap. They were certainly ground pounding, thunderous machines and remain very popular today in the collector market despite the poor fuel economy. But, if you are buying one of these for a collectable or just to have and enjoy, then I guess fuel economy is low on your list. One thing for sure, the power off the line was impressive and could pin you to your seat. But in my travels across the country, there are some stretches of highway where you could run out of gas long before you come across a service station. Still, a big block Corvette is one of those automobiles that just have to be experienced to be fully appreciated.
