Im building a 540 cu bbc with a F3 procharger on it, was wondering what would be the best comp to go with? By the way it will be intercooled

I would say anywhere from 9.5:1 to 11.5:1.

You perhaps should be thinking..."ALKY"Why? What's the real difference Spraying lets say a 500hp shot of Nos vs a F2 or F1 pro charger with a 3% to 6% over drive. They both increase cyclinder presure enormisly.

compressed boost = hot air

Nitrous = cooooold.
