76- 4oo engine Can i get 500-550HP stock exhaust

There is no argument as far as I'm concerned. Any of the big blocks require headers at 475 or more HP, why would you add a big assed cork to the engine, and a minumum 2 1/2" exhaust system. A B Body sleeper is next for me with a stoked 400 or 500 (probably 400) and long tubed headers with 3" exhaust and she'll be nice and quiet with the restrictive mufflers up and until the second I open the electrically operated dumps just up stream.:burnout::burnout:
