blades are set from rons at 10 thousands . i shut the bottom off and pull the cable at the same time. what are you talking about when you say running a loop line. my return line comes out and comes straight to the top of the tank. the plugs are ngk 10 . the distributor is msd the coil is msd everything is firing right no missing or acting up just cant really tune it cuz the egt is saying its 1500 after a pass on the tale tell . and its hard to start. like this thing is done pissed me off that i am thinking about sellin the whole car. i have been trying to get it right since the being of march i have done lost out of points for the season . i dont know if the egt is right or just throwing a false reading cause at 1500 i think the headers would be cherry red and burn some stuff up
