Hp with this setup turbo 406sbc? Im thinking of turbo our sbc. Its a 406 Forged pistons camel hump heads 2.02 1.60 valves has lopy cam I dont know specs. Planning on 12 psi on 103 unleaded octane. Any one have a clue on the hp it will make. It made 575 Rwhp on 6psi with a B&M blower. Also what size carb should i be running? It has a 750 double pumper but I think its to big. It runs rich very rich right now.

the carb is not to big,you just need to rejet it. as for the 406 itself,you are playing with fire at your curent hp level if the mains aren't splayed and even then quite a few crack between the cylinders with high hp/tq like a turbo or nitrous will give you. why not just change pulleys on the b&m if it isn't maxed out or is it sold ? good luck whatever path you decide.
