Pertronix Ignitor Problems... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey Everybody! First time on the site and I'm loving it! I have a '69 GMC 1-Ton Longhorn, SM465, 104,000 original miles. I just dropped in a new 350 w/ZZ4 lo-compression heads, big lopey cam, holly carb, and the latest upgrade was the swap from good ole points to the Pertronix Ignitor II and a new Flamethrower II coil. I am apparently the only person on the face of the earth whose performance has gone DOWN (the truck's performance, not mine!) by swapping out the points! Pertronix has no ideas, nor has anybody else I've asked. The cold starts are worse, it hesitates in the lower RPM's, and the mileage is worse than it already was. The plugs, wires, cap and rotor are fairly new, all the clearances for the Ignitor module meet their spec's... I'm lost. Can anybody help?
