    Not published, but Jim sent me an e mail that the engine made something like 30-40 HP less, and that is what prompted him to tear it down and inspect it. That is when he discovered the worn #4 main, and the web problem. From what I remember, there was no crack, but a weakness in that part of the block that caused that main bore to go out of round on the last torque increment. Maybe Jim could explain it further, or better.

    Larry, not to sound like a jerk. If you plan on cool right sea level day, your car is worthless on any other day then. If I was you, I would document every single pass you make. Like a pro drag racer would do. For one year. At that point you can always go back to your log book a and look up your weather and sea level and put that tune in it. This away you run more content. For example, I know someone in the Buick community that lives up by Mile high drag strip, they are always taking measurements of everything. Once they leave to lower level he does the same thing. He is very content now and wicked quick in his car. It weighs almost the same as factory GS skylark . I understand your car is a street driven car, if the whole interior system is correct, you won't be off by much once dialed in.
