I have just got a shiny new speed demon 650 carb with mech secondaries which I will be installing in the morning. The present set-up is a 600 holley on a weiand stealth manifold, but has a half inch edelbrock wooden spacer. Should I use this with the new carb, or am I better just plonking the carb straight onto the intake m/f ?? (with a new gasket of course ) Also I am running an MSD set up with a vacuum advance on the distributor. With this new carb would I be better removing the vacuum advance and going just mechanical ??
Any advice gratefully received.
