Ok lads, I think I f'd somethin' up here. I recently installed my 69 440hp with a brand new engine harness. I wired a summit ignition and coil into a msd dist. with new 8.0 street fire wires. I mixed up the plug wires. The motor bounced around pretty good, backfired, popped, and a nice little flame burst through the carb. I sorted out the plug wires now the engine runs like I'm missing a cylinder. I pulled all the plugs and they are all black. I'm also getting a good amount of white smoke which is I'm assuming unburned fuel. It starts up and idles ok but rough. What do you think I ruined? I'm workin on it now tryin' anything to smooth it out. 2:30 pm. pacific time.
