6. AMC Marlin 343
Back in the mid-1960s, AMC was famous for its lineup of economy cars and small sedans. This was before the AMC Javelin and AMX entered the mainstream muscle car class. However, AMC company management wanted an exciting, sporty car, so they turned to their Marlin model. As a result, the Marlin was a mid-size fastback with a design suggesting it was fast and powerful. The truth was the car only delivered mediocre performance. But for the 1967 model year, AMC decided to introduce a 343 V8 version of the Marlin with 280 HP on tap.
Despite the fact it wasn’t a lot, it was still enough to provide the Marlin with decent performance and driving dynamics. Today, 343 V8-powered Marlins are rare, but there are even rarer versions. Some had a factory-tuned 343 V8 engine that produced 320 HP, giving the Marlin real power. While it’s unclear how many of those special-order cars they made today, they are nearly impossible to find.
