wrench 87 Back Again
Indexing the distributor. This is going to repend on how much adjustment you will have once the intake manifold and other parts are on the motor. I have the 2 wires coming out to the front l/s of the motor. The best and easiest way to index the rotor phase is to cut a slot in the top of the distributor cap where #1 spark plug wire is going to be. Make sure the motor is on TDC of #1 cylinder and have the rotor centered on that terminal. If you put the hole in the top of the cap it makes it easy to check it with a timing light also with the motor running. Slotting is better than a hole. It will not hurt the cap. MSD caps are not cheap, Take the cap to an auto store and get a cheaper over the counter cap that will fit on the distributor. I think it's the old SBchevy ones that work from the 70's. Make sure you check the rotation of the distributor. Some are clock wise spinning others are counterclock wise. Set the wires up from there. Side note, basic tools to repair on side of road. Little kit in truck, cap,rotor,coil and module. Put in trunk with tools to do all these repairs. MSD caps have problems with the center carbon contact getting burnt out or breaking off. Some guys are running the gm caps with better longer life. This should help with this question, moving on----
