The motor was rebuild and set up on a engine dyno by J.W. ,and ran like a top at sea level. A few d.e. events and some street driving. The problem I have now I believe is caused by the elevation change. Why this motor seems to be effected so much more than my 3.2 w/46 pmo's is the mystery. From what I've read going down in main jet and/or idle jet one size should put me pretty close. The fact that the motor doesn't respond to the idle screw adjustment using either 55's or 60's is what's confusing (torturing) me.
