Ditch the carb and go tpi...way more torque in lower r's. And ive seen guys with built 305's (heads, cam, exhaust, tpi,) run high 13's. I dont know how well the carb guys do, because ive never seen any @ the track
I say stick with the 305...way less headache and still fast enough if done right.
later
