Thanks for all the input everyone. I'm looking to stay away from the machine shop in this one. The link that kowalski440 posted contains an interesting buildup, sort of what I'm going for. To summarize the article, they used an m1 single plane intake, headers, 850 cfm carbs, 516 heads. Made alot power surprisingly. I'm going to run a dual plane intake, a decent carb (850 seems a little much, not sure if my 440 will run that carb without being super rich), and either a .509 purple cam or the .484 lift can. A good port job on the heads as well to insure good flow (If a set of 915# casting come up, I will snag em, but otherwise it's the 452# or 250# heads I have.) And a set of headers as well.
