The intake I built from steel exhaust tubing was just an experiment for fun. I made it work and it seemed to work well. I had a 70mm
throttle body from a 3liter alfa romeo lying in the shop so I tried it. As for stall converters, they are v8 converters so they don't stall very high behind the L6. I've tried 2k, 3k, and 4k converters and the car feels quicker with the 4k. I don't have any dyno numbers out even track times to prove anything. The last time my car was daily driven it had the custom intake and 3k converter and it was a great daily car. I really appreciate your input Tony, I've learned a lot from you.
