hey Gary: I think we probably have the same cam in our motors as VPD puts the street performance cam in the ll engine. I'm curious what timing you use as I have no reference. I haven't had time to tune it and the gas mileage really was low on the first test. It did have ridiculously dirty K&N filters on it though. I cleaned those and am driving a lot easier to see what kind of mileage I can get. My old car gets about 20mpg and I would expect that or more on the 142 as it cruises in overdrive 600rpms less than the 122.
Thanks, Harry
