Who is BS'ing who?
Rant and throw caca all you want. But, the truth is my 408 Demon averaged 15.5 mpg on a 500 mile round trip This is highway mileage averaging 60 MPH, not stop light to stop light. I drove normal, no coasting and no slow starts, just a normal drive. It's a 4-speed with 3:55 gears, 950 Holley, TTI headers and 26" Nitto drag radials. Most importantly, it has a recurved distributor with vacuum advance and I know how to tune a Holley and set timing.
