My 200 is now running a modified 250 2V head, modified alloy manifold and a modded 350 Holley, it drives well to 60-70KPH, no hesitation, pull smooth then noses over. The carb has a 62 jet and a 5.5PV, i have no tuning experience with Holleys so first thing i checked was the fuel pump and fuel bowl, its was full and the screw removed on the carb, the carb bowl was full. I was going to have it dyno tuned but don’t want to find out i need a new rule pump. Does anyone know what the factory glass bowl type full pump PSI is? What does a 350 Holley need PSI wise. I can borrow and try and set up a autometer fuel pressure gauge and either put it on the front window or rig it up inside just see what its shows. It will just be some mucking around, maybe a PV change. I did screw in the mixture screws yesterday all the way in, then backed them out 1.5 turns, now its blowing a little soot out the exhaust, so i can adjust that some more. Apart from that it will be days before i can get a vac gauge set up. It drives fine, its just under acceleration as the revs are rising it noses over, like its out of puff or fuel
