Re: Timing detail for '39 Six

HH has it correct. But, note also that our modern fuel's octane is higher and other parameters are different from that available in 1939. Further, your distributor mount has a graduated rotational gauge for which the owner would adjust to compensate for the variation in the gas they happen to get. Open the hood, loosen the distributor while engine running, tweak until the engine sounds good, tighten distributor mount, wipe off hands and clothes, jump back in car and drive. Imagine asking owners to do that today.

So, I suspect your mechanic may already know this, but consider the factory spec as a good starting point from which you may need to adjust.

I hope this helps.
