It's a Hornet first it's not a truck, just an FYI. Second the entire rear end is closed unlike just about everything else today. It will likely come with 2 gearing options. There is NO adjustment for moving the motor, they come with 2 pinions and 2 spur gears and when you build the tranny you decide which ratio you want, small pinion w/ big spur or bigger pinion w/ smaller spur. If you use the stock motor that comes with the kit it's really a choice between slow and slower, either way it's not going to be very fast by today's standards. Remember that this car has NO slipper clutch and was designed almost 30 years ago, it can't handle much more than the stock motor that comes with it.
