Kind of totally and completely goes against the grain of vintage racing
doesn't it?
These types of transmissions aren't legal in many clubs, and Ribcase
gearboxes can be very reliable up to 130 - 140 hp, which is as much as any
legal 1275cc engine is going to get anyway. But if you're running in SCCA
GT type racing, more power to you! That's one of the biggest differences
between vintage and modern racing - we run what we had in 1961, you can run
what you can get today.
