Performance timing

Mattax posting#48

I followed the instructions after engine fully warmed up and running 92 octane no ethanol fuel psi 6 and vaccum gauge reading 18-1/2 steady not fluxuating! Idle in park 1000 rpm and vaccum port on distributor plugged off
Time light on 0 on dial and timing reads 30º at the 0 mark on timing cover tab.

In drive tach at 600 rpm and timing reads 24 º and in neutral tach reads 900 rpm timing reads 25 added 250 rpm's = 34º at the 0 mark on timing cover.

Snapped the throttle to 3000 rpm timing reads: 44º give or take a degree?
