I agree with the above posters on running a quality unit PLUS a tranny cooler.
I run a TA 10" tight unit now for 5 years on the street with 3:91's and 27" tires (3500rpm unit) and no problems so far. I also have a temp gage so I can watch the running temp of the tranny with the converter. Call Paul Forte at Turbo Action and he will ask for all of your info.

Junky:
With your new cam, I would bet that you won't be able to wipe the smile off of your face if you went with a 3k+ converter.

With all of the bolt on items that I have thrown onto my car in the last nine years(5 carbs,2 intakes, 2 cams, 2 ignition systems, even 340 HP manifolds to TTI headers[second place!]), this 3500 converter is by far the most "seat of the pants" improvement that I have seen.
