I think with the number you are after the SRT trans is a great investment. There isn't a quater mile track in my area, just a couple of 1/8 mile tracks which doesn't interest me. Most my launches are on concrete texas roads and a few black top ones. My tires are Yokohama Advan S4's. I thought the ratings I posted above were flb pounds and not Nm's since the V6 was shown at 330 flbls which is what I thought it was. When I got the V8 running Chuck Norris warned me a few times about needing to change the tranny. I had 330 ftlbs which is a little more than an SRT but my torque with very broad and flat. I have been very impressed with my trans. The first sign of these trans going bad is a delay in the 2-3 shift which I don't have. I will probably build a frankenstein trans by using my gear set in a V8 trans.
