how to install dizzy and set timing no HEI
Ok I see all day long about hei distributors but what about external coil dizzy. Is it the same for install put a flat head on the oil pump shaft turn it to cyl #1 on tdc comp line the mark on the balancer and go from there.

All dist install and time the same; type makes no difference
Dist rotor must be pointing at #1 plug wire in the cap when engine is @TDC on the compression stroke

External coil distributors are HEI too.

Actually to set it properly, the rotor should be pointing at the plug wire on the cap when the timing mark on the balancer is on the preferred ignition timing. If it's set at TDC then the timing is retarded.
Lets say your base timing is 10* BTDC. Bar the engine over until #1 cylinder is coming up to TDC. When the timing mark is at 10* BTDC, stop. Now drop in the distributor so that the rotor is pointing close to the #1 spark plug wire. Looking under the rotor at the pickup contacts, line up the contacts and clamp the distributor down. The timing is now just about perfect. Install cap, rotor etc and the engine should fire right up. Timing may have to be adjusted slightly to fine tune for chain stretch etc.
As stated above, it doesn't matter what type of distributor you use, how the timing is set is always the same.
