Here are some new numbers from one of my local buddies. Planning on using them on a 455 with dish for a '70 Firebird street car as soon as Butler gets to pistons in.
Close to what I think mine are. I flowed these in their virgin stock form with RAIV valves and picked up flow with a "flat" D port intake. Not sure they swapped them in here.
