Tony, your job is safe with me.
I can't stand to drive 55 MPH on the Interstate making every one go around me and I don't care much for those in front of me that do.
We travel many scenic highways where the speed limit is 55, but with a few small towns thrown in, there is no fuel savings.
I did OK with a 350 for several years and if he 450 won't do what the 350 did, MPG and pulling power....I found that used MH are easy to sell
Please continue to share your information with us, there are some that enjoyed it. I know your formula could work, it is nice to hear that it can be done.
