What supporting mods will you be running? pump, e85 race gas? The stock injectors on pump with big cams and full boltons( fast 102/102 etc) are when they reach their limit( stock fuel pump is good to 650ish whp). Also please define what you mean by "streetable". Do you want to drive like stock or are you willing to give up some low rpm drivability for power? Also are you looking gobs of low end torque, high rpm power or a mix of both? I would contact either shop and see what they would recommend for you as they both have a large array of cam selctions.
