I finally added a vacuum pump to the 65 and now I have power brakes. I did not have enough vacuum off the motor. I can now foot brake the car to at least 2k for take off. I tried 2k yesterday on the street. A little spin as I took off. Much better that 1500. I will try even more rpms at the track on Friday. I have heard that a little spin at the line is good. We will see what my 60 times are.
