Re: Who has a 427 gas in thier bus??
just got back from a trip to and from Fayetteville AR from Columbia Mo and seems the bus likes 3400 RPM the best @ 60 MPH. Haven't done mileage yet. Have your read my information on better performance? Try a gallon of Lucas and see what you think. If you increase your tire diameter you will loose power on the hills, nothing is free, everything is a compromise. Yes I have a 427, 640 allison and 6:83 gears with 40" tall tires. sportyrick
