I agree, that's why I suggested comparing them in the same weight car. One could also compare dyno numbers. At the end of the day a RAIV would kick the crap out of a 2 or 3 and the SD-455 would be...

Good info.... I think the deal breaker would be a true stock 13" converter. The RAIV cam is pretty much dead below 3,000 rpm in a 400 and I believe the RAIII would have a bit of a compression...
