I have run blown sbc on the street for years. I will give you some advice in a bit after i rest!!!! Just got home from a steel erection job for DPS.
ps i run up to 10-12 lb boost on with 93 octane. Proper jetting and correct timing and a good cooling system. Unless ur blower is a aftermarket it is not going to put out more than 10-14 lbs of boost max. Being in a street car it will put less strain on the engine, since you will get little traction.
Be back later
