I'm building a '73 F100 street truck. I have a carbed 347 with Gt40 heads and X303 FMS cam, and a c4 tranny. I'm planning on running, probably, somewhere around a 26" tire. Truck weighs 3900#. Any recommendation on gearing and stall converter? I would like good off the line accleration, but don't want to hurt highway cruising too much. I know the cam makes power in the 2,800 to 6,200 range. Currently I have 3.25 gears, and the stock stall. I'm leaning on staying with the 3.25's with the 26" tire, but just looking for suggestions.
