Running alky now, but can I "safely" run race gas with 14.1 and appropriate jetting/ignition changes?
Thanks a bunch for your input!
If you are going to run race gas Sunoco Supreme 112 is plenty for a 14.1 to motor. My engine that I had two years ago was a 469 (0.070 over), GM 188 iron heads, 13.8:1 , and a 1000 cfm holley. On the dyno I tuned it on VP C14 and then switched it over to Sunoco 112 and I made 11 h.p. and 13 ft lbs of torque more on the 112 Octane fuel. Here is a link to Sunoco's website for the 112.
