hey pooch, i have a question, when looking at different grades of fuel what should one look fr? for example should i just look at octane numbers, specific gravity, r/mon, what about when comparing one brand of fuel to another?, i just want to make a edcuated decision, also i have a n/a motor 505 big block chevy, i go no higher than 7500 and have 14-1 comp. is c-12 good or do i need c-14? thanks in advance.

C12 would be fine in your application. I suggest looking at the Motor octane. This is the true octane number of the fuel. Research and pump octane can be over rated and this will make you think you are getting a "better" fuel than you really are. Specific gravity is important for tuning. Especially when switching fuels. If you old fuel is a .750 and your new fuel is a .690 you will have to rejet because you will be lean. The fuel is that much lighter. Let me know if you have any other questions.

Thanks,
Jason
