NOTES: The compression ratio of this piston is 10.75:1. We recommend that you run 100 octane minimum for optimal engine life. You can accomplish this with at least 50:50 ratio of 91 OCTANE (or better) PUMP GAS:RACE GAS. Higher octane fuel burns cleaner and improves engine life -- and it s a lot cheaper than having to rebuild your top end!!
