Does timing affect boost?
Does timing affect boost? too much timing kills torque and increases chance of knock and not enough timing kills torque also. now boost this motor to 15 psi, the air/fuel mix is denser and most sources claim that less ignition advance is required. What should the timing be on a 440 Mopar? Try this: set initial timing (no vacuum) at 14, connect the vacuum advance to manifold vacuum ( not ported) then run the rpm back up and you should have around 32-36 all in. The reason for connecting to manifold vacuum is that as rpm increase, manifold vacuum falls...
