Looking for feedback. Is it too much for a stree car? Got a line on a nice 451pushing high 400 hp but wondering is it way to much to handle on the street. Would be going into my 68 Dart. It is an auto car, 727, 8.75 with either 3.91 or 3.23's. 235/40R18 on the tire rear. Not wanting to have to mini tube or change wheels for bigger tires to drive it. Have heard some say anything over 1/2 throttle or over 3k it's nothing but tire spinning machine. Like to get on it and have fun, run down a mustang or camaro light to light but dont want to be loose and heading into the ditch whenever I get on it .
