Hey Greg: The beast sounds fine in the garage, but I am still waiting for some dry roads before I turn it loose on the street. Tomorrow looks like the day. I'm going to visit Ted's tomorrow morning to see if my A/F mixture is a little closer to ideal. I think I might try a run with my S&H air cleaner attached and one without (since I don't have Bill' velocity stack). If you're not busy you can come over and kibitz.
Your big K&N air cleaner stopped the bonnet with a 1 1/2" gap before getting to the latches. Just a tad much. The Ford Racing air cleaner looks good, but is only 1" larger in diameter than my S&H. After lots of measuring and stuff I think I can get an 11" x 2" air cleaner in there. I'm going to call K&N and see if they have something close. It wouldn't be perfect, but it would be a big improvement over the S&H. How much did you say that new air horn would cost?
