This is basically a semi F3 conversion and is gonna be something that StephenRC45 will be trying.
The RS rotor will allow the engine to spin up faster 'cos less weight on the crank. The RS PGMII obviously gives good timing with no restrictions, but depending on year maybe need retarding for unleaded fuel.
The big carbs have been done by many and give good top end power, especially on a 'built' mota.
You'd be looking at 70+ ponies.
