Is that 37-40 with the vacuum unhooked, I assume that a pressure setting on these cars is usually done with the vacuum unhooked? Also what is a good indicator of whether or not I need more or less psi? Plugs, pop out the exhaust, etc? Man thanks alot!!!

John, it is set with vacuum off 37-40. You need to read the plugs a nice light brown color is nice and drive the car to see how it feels, it is feels like it falls flat at high rpm it may be running out of fuel, bump it a little and drive it agian, Your want to run the car as lean as it needs to be safe this will make maximum power.
