Hi Tim. I hope you got the reprint of my magazine article I sent you. You have a wonderful website, as I said directly over the telephone. Your car came out great in addition. I sent the link to the Weber guy in Chicago who has worked on the 48's and 58's on my engines for almost 30 years. You used an O2 sensor for your testing. His dynomometer is a T bucket with a weber carbureted small block and another with a Weber big block, for ease of service/tuning. He calls it his seat of the pants dyno. He has spent over 40 years running the devil out of that car trying combinations , recording data, and making changes after change after change. Thousands of hours. His combinations have eliminated popping, smoking, fouled plugs. That never happened on the engine dyno with my engine, with his intial set up, and never in the car. The horsepower numbers just got better and better as he continued with minute changes on the engine dyno for days. There is no progression cross over stumble at all. Pulls straight through in third gear from 1200 to 7000. Not much load though, as the tires are spinning most of the way through. The best idle with a four barrel that we could get was 1300 rpm, before he arrived. After manifold change and adding the Webers, idling was now at 900rpm with 280 @ .050 cam and right at .700 lift. As soon as he saw your idle fuel jet / idle holder discussion he knew you were closing in on correct concepts. I'd like to arrange a three way telephone conversation to discuss your progress, and probably expedite your end point .Thank you again for adding and helping so much to the Weber lunatics here in the Cobra world.
