Is there an existing design (besides the Mustang and Spitfire scale
replicas) that would nicely take an iron block SBC with a belt redrive?
I figure that would be very popular with builders with hot rod
backgrounds, especially a two seater like a little T-6/Vibrator/Provost
trainer. True a smaller engine would make for a more economical design
using a smaller engine but fuel is still relatively cheap, compared to
everything else in an aircraft.
