On trouvait les "Ram" de ce type (long ram manifold de 30" ) en 1960 / 61 sur les "performance cars" Mopar: Chrysler 300 F / G et en option sur les Desoto Adventurer / n'importe quelle Dodge ou Plymouth si on commandait l'option . Par exemple chez Plymouth le "sonoramic commando" 361 ci (310 ch) coûtait 389 $ et en 383 (330 ch) 405 $ . Le 413 des 300 donnait 375 ch. (400 en option "short ram" )
Pour le bruit je ne peux que recopier ce que disait l'essayeur d'une Adventurer. " ... Opening the throttle at any speed hurtles the car forward even quicker than using a passing gear would ... Throttle repsonse is almost instantaneous and even though the transmission is automatic torque is relayed to the rear wheels nearly as efficiently as a stick shift... One thing no true power enthusiast will overlook though is the engine 's vocal reaction to power. When the throttle is opened the ram manifold produces a vibrating sound similar to those made by dual exhausts. This resonance is not harsh and grating. Instead it is a low, throaty rumbling indicative of power... "

Avec un commentaire tel que celui ci ça donne vraiment envie d'en entendre une ....
