race fuel

My new 331 has about 11 to 1 compression. Should I rune race gas with this or is 93 octane ok? I know I should be able to run more timing with race gas. I also plan on running a 150 shot on it.

93 will be fine. im 11:1 with my 347, have 10 degrees base with no problems. Just remember to pull about 5 degrees out for the spray.

11:1 with nitrous = race gas. If you tune it to run on 93 octane, the performance will suffer.

Use good fuel so you can safely obtain the best performance.

Best of luck,
