I had this custom built by Midwest Performance Convertor for my 1972 Chevelle about 2009. It is 2400 stall for the TH350 tranny. I improved my ET by a half second with this convertor!
Was it a stock convertor you took out when you put this in? Did Midwest say anything about using it behind a big block? Looking to replace a "Saturday night special" convertor behind a mild 454 with a th 400 trans.
