Show me your 340 ignition wiring looms/routing

Johnny, I like those spark plug wires. What brand are they?

Thanks

MSD 8.5 Super Conductor wires. 31309 in black.
The black wire set seems to be harder to find.
They might have discontinued black, but red is readily available.

Nice. Some people say its a retard adjustment but if you center it I would call it a timing adjustment. For example if I ran pump gass vs racinng fuel. Would you agree based on your experience? My application would be actually summer heat in AZ vs winter. We run the cars here all year long and there could be as much as an 80 degree swing in the valley depending on time of year. So hot preignition is an isdue. I would love to use it for ping control

Yes you can center it according to the instructions. You can run it as a timing adjustment. It would work great for what you want.

Nice who makes the wire holders? What headers are those it all looks so much better than mine!
They are R&M specialty wire separators, not sure if you can get them anymore but I have never cooked a plug wire with them... let me know if they are still available.
The headers are 20 year ol TTI Chrome step small blocks... they are in my old purple Valiant but I use them for Dyno headers as well
