I would like to know. can you get high geared rear ends for the P30 chassis? someday I would like to get a higher geared ring and pinion to get the rpms down a little. anyone ever done that?
I know where you can find 10+ mpg for cheap. There is a '78 Revcon in Colorado for sale for super cheap. It needs brakes, tie rods and front suspension wear parts replaced. If driven at 55 mph, it should give a very solid 10 mpg, assuming the engine is in decent shape. Its got the Olds 403 in it, so the mileage wasn't bad with those. I have no idea the condition of the interior, but if its typical Revcon, the upholstery will be worn, but the cabinets will be like new.
