I'm more of an Injection Girl then a Carburetor one...but it's my understanding that the Cascar(Prefix) is a better square bore out of the box than the Ritter , but the Ritter is better with work done to it, the Ritter needs some help in the back coroners , but it's worth 15/20hp above 7krpms.

Joe's dual plane is hard to beat under 7kRPMS and it's better carbureted then the MOPAR single (non-drag pak)

I've seen the XV Vs OCP Carb V Carb and Joe's beat the XV by an average of 10 under 6k but the XV topped OCP by 15 from 6500-7200 and fell flat after 7300 it almost looked like valve float. but that same long block ran up to 7800 in-till the valves did float , with a Holley Hi Ram and 2x4 top it also laid down an average of 55hp over Joes intake, with the peak being almost 75. that engine was a 397 (3.937X4.08) with eagle heads 2.165 In take an 1.60, exhaust cam was Bullet custom Lift: .629 / .640, Duration @ .050: 252 / 260, Centerline: 104 installed straight up.
