SB 318 Wanting to build for a 67 Dart GT

And I Sean where it said that with just some porting you can get these numbers out of the 302 swirl port heads.. The Mopar Engines book says that the home porter can expect improvements from 5-10 HP, but that the potential exists to get 50 additional HP out of the 302 heads..
They sound like a really good set of heads.. I wish I had the money to make around 350-400 hp out of it.. I talked to my buddy and it is a 727 trans with a B&M 2000 stall converter..
