    I have an 86 302 EFI that I have been working on and one of the things I wanted to check was timing, so I bought a timing light. Hooked it up to the #1 wire, disconnected the spout connector, marked 10 degrees BTC on the damper and started the truck. Readings showed more like 20+ BTC (just a...
