Okay. I pulled out the performance cam and reinstalled the stock one.
Stock measured 1 3/8 inches on the base circle and 1 3/4 on the lobe.
The perf. cam was 1 1/2 on the base circle and 1 3/4 on the lobe.
Seems my 289 needs the smaller base circle. The larger base is for newer engines.
Now back to valve adjustments. The book call for two turns after the pushrod is finger tight. Any reason not to do this??
