I have a 306 Efi 5.0 block 10:1 comp, 4.66 Lift cam stock heads and the motor is refreshed. I will be running 93 octane in this motor and I am curious what a good base timing is? A friend of mine was telling me about 12 degrees would be a good starting point also would 38 to 41 psi on fuel pressure be about right for this motor.
Thanks
