My '69Z just arrived in Tampa, FL from San Francisco. In Tampa, the car will not rev past 5,000 rpm. It lays down and starts to miss. The car was dyno tuned in California just before leaving and pulled to 6,200 rpm no problem. I did not, however, take the car past 4,500 on the street after the dyno test. We did jet down quite a bit on the dyno, so it could be too lean for the change in climate. I haven't had a chance to look at the plugs or timing yet, but I'm assuming they are right where I left them. Any thoughts?
