Where are you from? As your zip code doesn't compute here.
I did a engine for a friend of mine in TX. about 6 years ago it too was a 360 .030 and with a bad carb and in the worst air conditions that you can imagine it still ran 10.88 @ 126 @ 3,200 lbs. but it had a small roller cam like .550 lift and 240-250 duration @ .050. It had KB107 pistons and a set of W-5 heads.
