I screwed up! I have a 69 camaro with a 73 350 v-8 engine that came out of either a Chevelle or El Camino. Anyway, I changed the plugs and placed the plug wires not as they were, but according to a diagram for 69 Camaro v-8. Apparently, this is not going to work as the car will crank, but not fire..I heard some popping, so I stopped. I didn't write down the prior placement, and so, I am lost. Can anyone direct me as to the correct plug wire placement? I have an HEI distributor. A diagram would be appreciated. Thanks!
