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.
canfield 220, with a newer head like an afr or professionally ported I’m confident I could have been knocking on 600hp. The 3500 stall in a full reverse manual th350 would only get yo to 2600 on the trans brake so definitely needed to change that to get up into a good launch rpm. I think it’s meant more for a manual tranny anyway.

Muff mod the 500i and level the playing field.
Retest

Thought it was stock, then I realized the muffler had a deflector brazed on the can. That is why the title dosent list "muffler modded"
The 500i matches or best the 390 once it is muffler modded.

How much hp and tq did the muffler modded stock 462 make? I forgot.

Honestly don't have the numbers off the top of my head. But it made more hp than the stock 500i. Tq would be close
