Consensus
Mopar should have built both a 340 'Six-Barrel' and a 440 'Six-Barrel' for the 1970 Duster, and a 'Race Hemi'.
The 1970 Cuda and Challenger should have been made available with
'3' versions of the 383, and {no 340's for the heavy E-Body}, '5' versions of
the 440, a Street Hemi and a 'Race Hemi'.
