I am driving from Chicago to Reno today. I did 22 hours in the seat and I have 700 miles to go!
I am having some cooling issues. I feel I am running hotter than I used to. I did have a lean running condition and I think I am out of the woods on this one. I installed an AFM meter. I had to boost the fuel pressure to get to 13.9 to 14.4. The other thing I did was I used Brad Penn 20 W 50 oil. I was running Royal Purple 10 w 40. I used the Brad Penn because it was available and this oil is supposed to be the oil to use (but maybe not the viscosity) Could this be causing a heating problem? I think an external oil cooler may be in my future. FWIW, I was near the red in the early morning cool hours pushing 70. Once I got to west Nebraska and Wyoming, the heat became a real issue. I plan on Being in Reno for more than a week, anyone want to connect up. drop a pm. I would love to hear form anyone here |

Sounds like changing the dizzy is your problem. Re time the engine to 28 degrees BTDC at 3500 rpms with hoses off and plugged. Advance timing will heat up the engine.
