gap question for TFI

[tc]

What do you guys gap your plugs to when you do the TFI upgrade? I think I heard that it is 45 for the F350, or could it be 35 for the FSJ 360? thanks

I gapped mine at 40. I have only driven it about 50 miles so far. It rund good, but I plan on pulling the plugs in a few weeks to take a look. I have the AMC 360

I run mine at .045 with no problems.

I gapped them at 45 and it runs great, just wondering if I was supose to gap them at 35 instead. thanks

When I was doing my TFI upgrade I did a little test by installing the new plugs gapped at 45 first. The engine would not start with the original coil. Put in the TFI an it fired right up. This don't have anything to do with your question but I thought it was a neat discovery. smile.gif
