This will be short & choppy because I'm thrashing to get work done and retrieve my brothers car hauler, it blew a tire and is stranded. Story when I have a moment. The AED 950 flows 820cfm, all Holley based "950" cfm carbs flow around this number due to there being two HP style main bodies: one for 750s and one for 1000s. The 950 is a 750 main body with the bigger base plate. I assume you have checked the fluid in the 200 trans. Have you contacted the manufacturer? They may have troubleshooting tips. You know I'm all about manual transmissions, but you have some coin in that 200, and a manual conversion is not simple (yet not terribly difficult either). If I were to buy a T56 today (and I'd love to for the '80) I'd buy it from one of the two recommended builders on the LS1tech forums. I'll send you the links off list. And thanks for the kind words, you don't owe me anything, other than for YOU to get into the 130 club!
