I would just like to get some feedback concerning the vacuum gauge readings I recently got off my 1966 425 hp coupe with a Speed-Pro Sealed Power (part #CS-165R) factory clone type cam. I believe the readings are satisfactory:
At 900 rpm: 15 inches of vacuum
Also, when I slightly adjusted the idle mixture srews on the carb (Holley 3247) I got the vacuum reading up to 16 inches. By the way, I took the vacuum gauge readings from the fitting located on the top rear of the intake manifold. Thanks.
