Give him the body from the one roadster and take the R16 from it.. So many motor swap options for it. :lol:
as for the measurements the motor is about 16 inches from front to back, the width with carbs I'd say is about the same, and it is about 18 inches tall. With transmission it is about 51 inches from front to where the drive shaft begins.
I've been trying to find the pictures, but if its not raining I'll get you more exact measurements as my camera didn't have the photos I took for measurement.
