high water temp issues

1. Double check your timing
2. Get a shroud and put back in your 180 degrees therm, SB mopars like to run from 180-195 degrees for optimum performance.
3. Move your fan farther back from the rad to allow for more air flow over a wider area, you'll be surprise how much that helps. I also had a heating issue and once I installed a shroud and moved the fan back about .750 no more heating issues...
