the rotor has to be pointing towards number one cylinder when it's at TDC compression stroke. You find that by taking out the plug and having someone bump the motor lightly--with the ignition disconnected--and feel for the biggest "puff". This is basically telling the distributor that you want it to fire when the cylinder is at TDC compression stroke.

Actually, it doesn't really matter which way it's pointed as long as you have the right firing order and the terminal that the rotor faces goes to whatever cylinder you happen to have set on TDC compression stroke. THe only reason they say to point it that way is for ease of setting advance and making the wires look pretty.

From there, Chevy Guy's firing order is where it's at. If you forget though, its usually in a stock 350's intake casting on top of one of the runners. Oh, and with those high output coils, you definitely don't want the wires laying all around the engine comaprtment. Keep them off of conducting metal and away from the headers. Good luck.

You don't point it at the # 1 cylinder. You point it at the # 1 cylinder wire terminal and it can be where ever you want it as long as it is in time. The book says it should be pointed at the # 4 or 6 cylinder. The wires go in the cap as per firing order going clockwise. The vacuum advance should be on the passenger side, pointing forward. HTH.

Good Luck


If you don't make mistakes. your not doing anything.
