What head you have on the 377? Dart 200? You running and auto? I don’t disagree that that the 377 is a top end motor,,with the 6 speed it’s easy to get in a good rpm range, and still has enough torque to pull 6th at 55mph at 2k but you can also drop it into second gear and be and still to 80mph, third gear is 3500 at 50mph and sweep to 7500 at 108mph. I like the rev range. And even at that with decent street tires is wants to spin at 50mph at 3500. With an auto, torque is king. Unless the auto is worked over for the need, like a big converter and manual valve body. I like the personality, and the idle chop, lol I would never want the motor in my 72 blazer, but a 3100 pound car 6sp and 4.11’s it’s fun.
