Ok, had car calibrated. Steady speed at all RPMs were at a steady 12.5, but when WOT it goes rich. Has .077 secondaries and I did not have any smaller ones to try. I have ordered and assortment of secondary jets to try a few steps smaller to see what results I get. Car runs great overall and starts and pulls hard, other than being Fat WOT. Secondaries vacuum butterflies are opening, had to lighten the springs to allow them to operate. Any suggestions on what Secondary jetting to try first, AFR is at 11.4 at WOT. I have ordered .075,.074,.072,.070

Attached WOT dyno graph, you can see it goes fat quickly. but power for the little 302 is decent as is the torque.
