[300exboy #15]

does any company make a 12:1 or 13:1 compresion piston for a 300ex and wat do you need to run that wat octane wat other engine mods and any thing i missed

12:1 most likely a 50/50 mix, 13:1 50/50 mix to full race fuel


now thats not super accurate, different quads and your climate determin what octane you sohuld run
