Because the Chevy rotor rotates in the other direction, the distributor needs to be turned in the opposite direction, or counter-clockwise, in order to advance the spark.

Which way do you turn the distributor to advance timing on a Chevy 350?

A: Because Chevy distributors revolve in a clockwise direction, you will need to turn the distributor in the other direction to advance the timing. Bringing the timing up to speed in order to facilitate cold beginning is only going to be helpful if the timing was originally set too slowly.
