Ignition timing for 351C
I am (still) trying to find out what timing setting to use with my MSD ready to run dizzy. Eg: initial advance and which spring/bush combination to use. I am experiancing pinging (closed chamber heads opend out) at around 90Km/h cruising on and off throttle. The vacuum advance is still there and I am reluctant to take it off.
