I have a Crane Cams FireBall XR700 and a FireBall LX91 coil. I have a header (4 into 1) and a Weber (32/36 dgav converted to dgev). What is the best plug for this set-up, the Bosch platenum? The car also has a ceramic type ballast resistor made by Delco and has the stock resistor wire bypassed. Does this sound correct so far? I was wondering if I should also replace the resistor to a different type. Thanks in advance. And speaking of advance should I be running at eight degrees of advance with this ignition system. I am trying to get the valve train tuned and need to eliminate any possible side issues with the new system.
