Can some one tell me if the HEI unit sold by Tom Langdon is a pointless dist. Also, what are the pro's and con's of using the HEI setup in a 6-cylinder, 235cu-inch 55 series 2 truck. Any info would be greatly appreciated. Oh, last question. When you set the points to .016-.019, aren't you also setting the dwell. In otherwords, there's no seperate setting for the dwell is there?
