timing on 360

Pull the vacuum advance hose off the distribtor and plug it so it doesn't leak.

Get timing light set up on #1 spark plug wire and aim at damper on running car.

Loosen distrib and twist it until the mark hits the 17 degree mark or use a dial back light and dail it back to 17* and aim light on damper mark until the mark hits zero when you twist the distrib.

Rev engine with hose still off and plug to 3000 rpm (This varies with engine build) and note total advance with dial back timing light set to 34*. The timing mark should come to the zero mark. Somewhere around 34* is what your looking for.

Re-attach the vacuum hose to distrib and rev engine up to approx 3000 RPM (This varies with engine builds) and note the total. It should be no more than 52*

Set carb idle, lock down distrib, road test, enjoy.
