- 73 loaded Q code car w/a 351 4v C6 it came with 2 cars in parts.
I've got a MSD box w/a Unilite distributor. I assumed I had a full 12 vt since this thing came with a Motorcraft electronic distributor. Starts and runs w/ a slight miss, then carbon fouls plugs. I'm leaning more towards the electronic side of this being the problem. I had 12+vt at the starter relay and assumed that I was ok. Now I'm 2nd guessing it. Maybe I should see more like 13.9 running. I've read 10 different stories on the net which wire to bypass along with where it is. I have a stock tach & read that was one place to bypass. The tach barely works at the moment. It reads 100 rpms when it's 900. Perhaps a tach adapter is needed. I can wait on that. One guy said back of tach to fuse block, another claimed it's from the ignition switch to the firewall. I assume from the ignition switch plug on the column mounted one. "I" terminal is supposed to be the resistance circuit after start. What's the best bypass method? I planned on 12/14 gauge with spades. I might have a 71 harness in it don't know if that was from a stock tach car. The difference being a pink wire no tach and a red with green stripe for tach. I see a red w/gn stripe at the connection for the column mounted ignition switch.
