how to get power from a 318

Hey scampgt440 I have a 73 Dart Swinger that when I bought had a hopped up 318 nothing too drastic, it still has the stock heads but with a nice port job done, a big cam, bored .060 over, 10.5 to 1 compression ratio, and a 600cfm edelbrock carb. My biggest concern for you is what size rear end do you have? mine had the stock 7 1/4 in. with 2.76 gears, and let me tell you what happend I was sitting at a stop light stalling up the converter and when the light went green i hammered the gas and let off the brake and the rear end went CAAABOOOOOM!!!!! I recommend if it doesnt already have an 8 3/4 to put one in if you are planning on souping up that 318.
