Hi Guys
As I had previously stated I had instructed the dyno operator not to exceed 6500 RPM. The engine had 12:1 compression ratio and a cam profile designed to give the most power in the 6500 RPM range. The dash in the car is very well laid out with the
oil presure and water temp beside the mechanical tach.

So what I am to understand from your statement is that you are supposed to run the engine past where the engine makes it's highest figure and keep going until you've hit the max MPH speed the dyno is set-up for? To me this sounds like it would run the engine into the ground with possibly both severe detonation and
oil starvation?
The reason I took the car to the dyno was that I had ignition break-up at 4000 RPM and was diagnosing the problem, it turned out to be a worn distributor shaft bearing. The distributor was replaced with a freshly restored original then the other two pulls were made that exceeded the 6500 RPM limit. My engine builder has stated that there are signs of valve float as well,
