How to Dynamic Time the Small Block Chevy

This video is on how to dynamic time your small block Chevrolet distributor, that would be after the distributor has been installed in your vehicle and using a timing light. During this video you will see me not remember to rotate the engine 360 degrees after I had adjusted the valves so that the distributer was 180 degrees off, popping back through the carburetor is how I knew that. When setting the valves you start out in the #1 cylinder firing position, set half the valves then turn the engine 360 degrees and set the rest of the valves, this puts the #6 cylinder in the firing position. If you do not rotate the engine another 360 degrees after the second set of valve adjustments and you install the distributor then it will be installed 180 degrees off. So now I need to remove the plug wires, cap, note where the rotor is pointing, lift the distributor, spin the rotor so it points 180 degrees from where it was pointing, and re-install everything. Notice I use tape to mark plug wire numbers for easy installation afterwards. Your vacuum advance on the distributer needs to be disconnected and the vacuum line from the carburetor plugged through the timing process, and the distributer hold down bolt semi-loose, my 1971 Chevy truck timing is set to 8 degrees before top dead center @ 900 RPM's. After the engine is running, turning the distributer counterclockwise will advance the timing and clockwise will retard the timing, verify your engines RPM's after initial timing is set then verify it again after RPM's are set. After the timing process is completed, shut the engine off and reconnect the vacuum line, and tighten down the distributor hold down bolt. Always be very careful you are working around rotating equipment, belts, and the fan, which in my case has no shroud! This video doesn't go quite as originally planned, but that's reality!
