I can tell you there is a huge difference on RPM with the 200-4R at the top end. I am running 3.23 gears, and the 350C I had in there until a few weeks ago was running very high rpm on the highway (and you probably could run 3.23 gears too Ray for more top end... you have the HP). There seems to be a much more dramatic difference between the 350C rpm at lockup and the 200-4R when the lock up kicks in too. Maybe it's because I have a higher stall converter now (1680 vs stock 1200?). But I can be cruising in OD at a real low RPM, and (because the speedometer reduction gear hasn't arrived) when the lock up kicks in, the R's drop waaayy down. I can't wait for my first road trip to see if I will break the 20 mpg barrier with +,- 300 HP. I was at 19.8 mpg @ an occasional 80 mph on the hilly highway with the 2.51 rear gears, 350C, and TBI in 2007. Sure wish I could afford to trailer it to the flats in 2013........ My goal is the Power Tour. I don't know what the 2013 Route is though. Do they have it set?
