Having ridden in the car, we can definitely say the Revology machines sound great and perform far better than a classic Mustang with a period-correct powertrain. Moreover, the handling and NVH qualities are vastly better than the vintage hardware we have sampled, even those with newer engine swaps.  Moreover, the car turns and corners better than a classic ever thought it could. Clearly all the work put into hand-building these cars is paying off.
