Cam Degreeing
get you a haynes manual or any tech manual they will explain it better than we can and they have pictures. With you gear set up i dont know I have never used one. With a chain just put the cam shat dot at the bottom and the crank dot at the top and line them up as close to posible and you will be good. You dont need a degree wheel or any of that stuff especial with it in the car it will be hard and most likely you will screw it up.
Waiting to hear this thing run. Hope for your sake that those pistons dont come apart.
