Carb change.....

No vacume readings.
We've veered off to the 'mostly track' lane. When the engine was built, and I ordered the carb, I did it with the idea that we'd be shifting around 63-6500 when all said and done. But since the thing pulled so hard and bounced off the 7000 limiter, we decided to add a stiffer gear and thought it prudent to go with the dominator to feed the extra rev's. The heads and the cam should be happy.
