A converter change is certainly not a problem, I have a reworked 10-3/4 hemi converter that was around 2800 behind a 500 horse 440. My flash stall on the current Dynamic is also behind an engine that developed 660 lb ft of torque, I wonder how much less stall it will have with the milder 493. I want enough stall to have no idle issues. I think I even have a stock Street hemi converter in the shop. If I went with the MP 528, the stock 10-3/4 would probably be enough. Carter, it sounds like it really works well for you and that is good to hear the voice of experience, I have that cam, so I may give it a try, but I am thinking maybe a touch bigger, My rockers are 1.5 RAS/Isky's. Your car is obviously an 11 second car, I could possibly live with a low 12 second car. But faster is always better!
