I have a 454 SO (not a police interceptor motor like someone else
) with 3.54 rear and a .68 overdrive. 2 weekends ago I did almost 400 miles going down Skyline drive and got 15.6 mpg (gets 9+-10 around town) with NO hard accelerations. My foot was ok but my ass was SORE!!!
We drank 1.5 gallons of water, used earplugs, and had a blast.
Patrick, the CACC Rehobeth Beach cruise is a blast. Do it!!!
