thanks Cliff,
modded the plug to adjust the APT on my carb and it is amazing the difference of throttle response, spark plugs are going tan. i've owed this 301tta 18 years then rebuilt the motor two years ago. i had 290rwhp but always lean. i can't wait to recieve your custom secondary rods. this will allow me to enjoy and have more fun with my car.
thanks again kevin
