I agree with comp....aar, I guess to me the .484 cam and 4.30's aren't what I consider "streetable".....3.55's max for a street car, as I consider a street car something I can drive on the freeway across the state.....

if you want a civilized, "mild" running car that can go that fast, a 408/416 is the way to go....if you want something that sounds meaner and you need lots o gearing and convertor that doesn't idle below 1200 rpm, then run a 340...
