During the last Bloomington tour my 1966 427 convertible was constantly being challanged by a 2006 ZO6 on every stop. During these events I noticed that every time my RPMs went over 4500 my engine seemed to bog down and even decrease in power. This seem to happen no matter what gear I was in. What gives? The engine had been rebuilt a number of years ago prior to myself and all the external parts(Intakes,carb,trans,heads, valves) are original.
Thanks
