In honor of the 10th Anniversary of your <blushing>absolute favorite automotive blog</blushing>, we’ve taken a look back at the previous winners of all our annual Muscle Car Match-Ups and pitted them against each other in a winner-takes-all Tournament of Champions.

And after the first round of eight, we’re down to the final four vehicles. Last round’s voting revealed some loyalties, as we saw all of the so-called underdogs go down. But now it’s a quartet of the best-of-the-best, so we’ll take a closer look at the semifinal round pairings below.

How to Vote in the Muscle Car Match-Ups Tournament of Champions

You can vote in one of three ways:

We’ll tally up all the votes by the end of the weekend, then present you with the Match-Ups’ championship round the following week.

1965 Shelby Cobra 427 vs. 1969 Dodge Charger R/T

There hasn’t been this much anticipation of a Shelby and Dodge pairing since the Omni GLHS! In the first round, both the Charger and Cobra won against their competitors with similar margins of victory, so this one may go down to the wire. There are plenty of considerations here, from the Shelby’s British AC heritage, to the Charger’s celebrity status in Hollywood. So what’ll be the deciding factor? Get ready to vote and we’ll find out together.

1970 Plymouth Superbird vs. 1970 Chevy Chevelle 454 SS

If you look up musclecar in the dictionary, there’s a good chance you’ll see a Chevelle. And the fact that it was available with the legendary 450 hp LS6 454 Big Block was just icing on the cake. In the other corner though, is Plymouth’s NASCAR homologation special which, thanks to its rarity, has made it one of the darlings of the high-dollar auction scene. Picking a winner between these two monsters is not an enviable task here, but someone’s gotta do it.
