Just my 2 cents....i drive a 94 cavalier for the fuel economy, im building a 71 monte with a supercharged 502 for the power, i have had a few people come up to me and ask "what kinda gas mileage is that car gonna get?" i tell them im not building a supercharged 502 for the gas mileage, who knows?, who cares? really? you know? Just my opinion but you know what they say about opinions...
