| Hi Dave,
What dist cap are you running?  I am using the side entry, I like the
way it looks.  Puddles started doing exactly that, missing at high Rpm's
.  Found out later the screws inside the cap holding the wires loosened
up causing the miss.  Retightened and wow what a difference.  I can do
7500 now no prob.
