Exhaust Backfiring

how are your plug wires and cap, any tracks in there? You got the AF meter, why not get your AF up so its not rich? Is that AF while idle or under load. Are your transfer slots so small that they appear square? thats where they should be. Edelbrock AF is way easier to tune on the car with different rods and step up springs.

Plug wires are good no sign of tracking in the cap. It might be time for a new cap and rotor. They are a couple of years old. Want to replace my AL6 with a new AL6-2 eventually.
Put a set of Doug's headers on this spring and the pipes are nicely out of the way of all plug wires. Plus I rap the pipes with Lava Tape. Good stuff.
