Sorry, that should say 120 degrees, not 180 degrees.

Hey barry,

There is a tab with marks (image below) on top of the damper. But I am making the tape more as an added assist and peace of mind to make sure everything is right on the money.

In my opinion, Chilton is a poor second to Motors, and Haynes sucks because the info is hard to find and is sometimes even missing. You can also go to a Chevy dealer and get the specs from them.
I've been using the Autzone website as a reference and it calls for 8 degrees BTDC. I can stop by the local Chevy dealership and ask.

This is where I recently hit a trouble spot. The last time I installed the distributor, I did in such a way that it now hits the intake manifold when being turned CCW. So I need to take it out and reinstall it while making sure it doesn't hit the firewall either.

After the last timing light turned out to be a dud, I waited and bought a fancy one (Equus 5568 Pro-Timing Light) and its features include "tachometer ranges from 249 to 9,990 RPM", so I am sure it will do fine at 3,000 rpm.
