As shown in my link the 41 (Betty Boop) is rocken and rollen down the road.
In driving her I at first had a lot of engine clatter (ping or spark knock) i readjusted her ign. timing and reduced it greatly but still have ping. We are running super unlead fuel. And base timing is on the mark. My question is how much advance should this truck have.
1941 216 standard shift. Also is the ball on the flywheel TDC or an advance/ retard of TDC?

I didn't do it, no one saw me do it, you can't prove anything! "Bart Simpson"
