Hi Fordsix community. I have rebuilt my 66 200 with a Clay Smith H-264-8-B cam, 108 degree ctr lobe, and a DUI distributor. The cam profile card indicates to degree the cam to 106 for best performance. When I degreed it with no timing adjustment it was 104 so I retarded 2 degrees to 106. The engine runs, but will not run anywhere in the range of the degree markings on the timing cover. I believe the last mark is 14 degrees BTC. The timing light puts the mark on the harmonic balancer at the 12 o clock position of the balancer for the engine to run best. Where am I off?
