from what i have found with major mods like heads and cam the bbk actually picks up a couple horsepower and couple ft lbs of torque. it seems if you have a ls1 intake its worth changing to either one of them. but if you already have a ls6 or bbk changing it would kinda be like ****ing in the wind. not a good decision
