commando cam .. how much will it take with stock specs ?

QUOTE[ well, you could build it to "Super Commando" (D-Dart) specs and wring out ~275HP out of it but youll need to wind it out with headers. Youll lose low end. Is it a stick or auto? Mopar would not cam it past what the factory exhaust would handle] QUOTE

Sorry, no "Super Commando 273". D Dart only. (Commando is a Plymouth term and Plymouth didn't have a D Dart equivalent.)
