yes the car runs fine both gauges are at 0 psi. no surging no idle problems im going to move the grounds directly to the negative terminal of the battery to see if this helps as far as a possible grounding problem per big chief i am getting 11.6 volts at the relay and fuel pump both are mounted near the gas tank. . as far as the plugs I did adjust the idle mixture screws i watched the Edelbrock videos.
