Stop in for a cup of coffee

If he’s having the FiTech control timing then the distributor needs to be completely locked out. It also needs a particular distributor. As I understand it the MSD pro billet or a clone. @Johnny Mac can confirm/clarify that. I bought the system from him when he was with Pace.

Morning @MomsDuster and @halifaxhops .
Correct, the OEM, and OEM type (pertronix) have limited success with providing a clean tach signal. A "pro billet" (msd clone) is best for timing control. Or a little hei, or cdi box, can be used without.
The "Mallory" or "Pertronix" types dont do too well.

Any of these, besides the "economy" titled ones.
