I have the Lee Petty Fury (very similar chassis) and I found it easy to set up except for the fact that there is very little room under the rear wheel arches. Seems you have fixed that with this one!
I used the Pioneer Typhoon motor in mine, it was an easy swap and gives it more brakes (but not to the extent of, for example, my Slot.It GT40 - it pulls up in a very natural looking manner for this kind of car). You just put the pinion on the long shaft that hangs out the other end of the can.
I used the B-NOVA conversion. Easy and cheap. I did the same to a Willys the other day. Both used the Sloting Plus SLPL 2130 universal standard guide with screw.
