Stupid Ignition Question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Here goes, How can I tell if I have HEI? I know there are probably some obvious signs, but I bought the truck as a whole so I don't know. It has a 79 truck 350 in it.
Thanks in advance for answering my stupid question.

8 plug wires on cap = HEI, 8 plug wires plus one in the center to coil (total 9) = points

If the cap is as big as a ice cream pail it's a HEI.

So this should be an HEI, right? Anyone recognize the color/brand?

Thanks Again

Looks like Accell wires but why the gray one?

probably cuz they were angle sockets at the plugs and one was in contact with the header.........had to use a wire with a straight socket.

blazerparts is right about the grey wire. Anyone know the brand of the HEI unit?
