Best Mopar engine of all time

BEST means different things to different people, and thats fine. i liked my 1957-58 chrysler 392 hemi. history note, the 1955 chrysler 300 of 331 ci, was the first american engine to make 300 horse power. and started the well known 300 chryslers 1955 throu 1965. any other car that says 300 is NOT a REAL 300. please remember when i say chrysler i mean CHRYSLER not dodge, Plymouth, desoto.
