Re: Plug Wire Questions..Need Help.
Hope this helps. HEI terminals look just like the top of a spark plug with a protruding tip that the plug snaps on to. Non-HEI / Breaker Points setups have a brass socket that the wire end sticks inside of to form a connection. Visually you should be able to tell the difference. However, if your setup is like mine, I have an HEI cap, and an Accel Super Coil with a standard brass socket type top. So I needed a special wire that was HEI on one end (for the cap) and the brass socket type on the coil end.
Here are some tricks for a small block chevy. Take a sharpie and number your old wires before removal. #1 cylinder is on the front left of the engine behind the drivers head lamp so to speak. The odd cylinders start at #1 on the front left down to #7 on the back left (1,3,5,7). The right side from the front of the motor to the back are 2,4,6,and 8. The firing order is 18.104.22.168.22.214.171.124
Then remove the old wires and pair up the longest new wire with the longest old wire and install it according to your sharpie mark. Can can also flip flop between longest pairs and shortest pairs. If you do this you're virtually guaranteed not to have to redo your work.
