When i was troubleshooting distributor i thought maybe rotor or cap so i ordered msd 84335 replacement cap and rotor set that msd support line told me was for my particular distributor. Still same problem as with old ones so im assuming not the culprit however is there a way i can test and see if spark is going from coil to rotor? Or another way to troubleshoot spark out of coil but not to spark plugs. Also thanks again for the input guys i appreciate it. I have hit a serious roadblock at the end of a build. Getting frustrated.
