C vs B rotor??

I have a question about real world performance.

I was lucky enough to score both blowers over the last decade. My interests have moved into the Top Fuel arena (which is seemingly requiring lots of funds to get started up ). I have had my alcohol motor up for sale as a complete package with little interest. On the other hand, there has been a ton of interest in the purchase of the C rotor on its own. I have a fresh from PSI B rotor that is a really nice piece. If I were to put the B rotor on the current motor how much real world performance am I losing?

The motor is a -500 521, Noonan S600 head, billet Noonan intake setup. I have learned that I am never going to be competitive in the outlaw world when I do run the car again in the future. But also don't want to kill the potential performance.

I am familiar with the rotor displacement and the shorter area in front of the rotors on a B, wondering how the B has performed for others.

TIA, Scott
