#4 Chevrolet Chevelle COPO 427
For most part, the standard Chevelles came equipped with 396 Cid V8 engines that could produce a 375 HP, but the retired racer, Don Yenko (who worked as a dealer at the time), decided to introduce the 427 Cid engine to this monster; this resulted in a 425 HP that could reach 0-60 in 5-1 seconds.
