Big Ed. Just a little. Sounds really nice.
Not quite the smooth as a Singer sewing machine sound that it had. I really don't think that I could have made a better choice as far as cams go. If I bring the car up to 40 mph and then let off the gas so that it switches into overdrive and then switch on the lockup clutch in the torque, the rpm drops way down to about 1100 or 1200. Then I set the cruise control.
So I wouldn't want anything more radical. I was surprised to have that much vacuum loss though. Used to have almost 21 in hg, now is just a little over 15 in hg. Not a concern, just a little surprised. Allan
