Before I run off and spend some more money, kinda curious if anyone has had an MSD detonation/ping from plug wire crossfire. I hear it at low rpm or if I lug it a bit, i.e. puttering into the garage. Knowing that the MSD box "throws" a strong double spark below 2500-3000 rpm has me wondering if I need some 'upgrades' as far as wire or dist. cap.

- 8479 small dia. billet distributor set to the 'E' curve but it still did it with the ho hum 'as shipped' curve
- 6AL box
- 8200 coil
- Taylor Spiral Pro 8mm wires (few miles, but 5-6 + years old)

MSD does sell an adapter to use the wide Ford style cap, but I have currently have the alternator pretty close to the dizzy.

No vacuum leaks, the Edelbrock 1405 carb is set identical to the one I had on my 356cid 351W so it shouldn't be lean, but......
