Help this thing is driving me crazy. Any one know how to fine tune the vortech style distrubutor? It is installed and motors running but I have a slight mis at higher RPMs.

You put a scanner/merc scan tool on it, notch the hold down to the diustributor to make it adjustable and watch "cam timing setting +/-" until you get it as close to zero as possible, at least thats how we do it on autos with same motor, Smitty
