OK I have checked the spray bar and tried a restriction in one hole, no real change. I drove the truck around the block it hardly made it. I am now wondering about the coil, I changed the charging system to 12 volt and I never put a balast resistor on the coil. I have an MSD coil on my SEC but it has an HEI terminal on it. The truck starts fine and idles well, I'm thinking the coil is breaking down and the increase in pressure is causing the problem?
I have to say at this point it has become worse and will not rev above the hesitation range. I put some fresh gas in and that did not help any either. I am going to pull the plug right now
