I have a 50 lb flywheel, a 35 lb flywheel, and a aluminum fly. The motor is a healthy 427 bbc 11.5 comp., going in this 21 fairly light cruiser. Just curious if there would be any noticable differences. I thought the 50 might give me a little more torque but I really don't know. Any experience out there.........I got a feeling someone has tried it......Thanks ahead of time.
