Hughes converters?

still no word from converter builders.. Anyway if you read from Hughes web pages it clearly says how to estimate stall speed. healthy, not overcammed bb should stall where they estimate, healthy not overcammed SB should stall 300 rpm below their estimation.If engine has big cam it even can stall over 500rpm lower that they estimate. so 2500 rpm converter should stall bit over 2000 on my 318.

btw do I need new flexplate, bolts, etc for custom converter or Hughes converter?
