You guys spraying a pump gas engine do you ever spray with 93 pump gas or are you always changing out fuels for the track...Smallblock at 9.5 comp !!
Gary my sons magnum 360 (all stock except for camshaft and carb intake) runs fastest on plain pump 93. I proved it to him we swapped out 110 race gas and it picked up almost .2 in the quarter mile.
