Ignition timing is alsways fun on a rod, so here goes. I always set a stock SB ford to 8 deg btc, +/- 2, so you are good on initial timing. Full advance should be at around 35 deg. The point of full advance is up to your desired timing curve, according to the intended use of the engine. For a pulling truck, full advance at a lower RPM may be desireable, for a dragster a higher RPM, street rod midrange.r The timing curve is matched to the torque curve for maximum power at your desired RPM. One worthy note: Too much advance will cause a spike in combustion chamber temps thereby melting plugs and doing nasty things in there. If you SB is only mildy built, then don't stray too far from the factory specs, but do run a cooler plug.
