Running stock eliminator with a smog 318 forced me to stop using the Sunoco 110. Without the compression, the 110 burns slow. I've switched to 260 GTX with stronger performance. With my 10.5-11.0/ 360 ,10.50-.60@125 I mix the 110 with the pump 93. The leaded fuel in much more stable that straight pump gas. It also keeps your carb internals from build up in the bowls and passages. I also runs cooler than straight 93.
