A French car, Facel Vega... was built starting in 1954 with De Soto Hemi's ( 276 cu in ) and the Chrysler 2 spd Powerflite trans which was quickly junked in favor of a 4 spd Pont-a-Mousson trans.
In 1956 they had 331 cu in hemi's, in '57 they got 354 hemi's
But these Hemi's were small potatos compared to what came along in the early 60's. The 383 dual quad wedge was making 390 bhp @ 5400 rpm and a monumental 485 lbs.-ft. of torque @ 3600.
