I'll just add again that I street (and track) drive an 8"ATI Treemaster conv in my avatar that flash stalls right at 5000 rpm. I've not had such a high stall conv until this one. I do NOT believe you need such a high stall speed as I believe
@abodyjoe gave great input on his and how something like that would be recommended for your combo.
Based on my experience with mine, I"m just reiterating that a modern high stall TC from a reputable company can drive like a stock TC until you drop the hammer. The avatar idles around 900 rpm and you have to keep your foot on the brake at a red-light. Pulling away in traffic appears and feels just like any stock TC. But apply some Wheaties and...hang on, your buttometer will be all smiles! And 160-170F trans temps on the street are certainly fine to me. You won't regret having you some 3200-3500 stall speed TC!
