From Phoenix to LA and back my 78 Z based Velo Rossa averaged 35MPG. Cruised on I-10 at 85MPH+ most of the way. I have flattops under an N47 head giving a compression ratio of approx 10.3:1. The higher compression must be more efficient.
The car got plenty of attention! Most everybody was wowed by the paint. Thinking that it was a secret blend. But in reality just 93 ford probe silver! I didn't show off the engine because we didn't have time to detail the engine bay after paint, just 1 day before the show! Tht was cutting it close. I took pics and will be posting on my website in about 1 week.
