1968 AMC AMX vs 1970 Pontiac GT-37 - STOCK DRAG RACE

1970 Pontiac Tempest GT-37 vs 1968 AMC AMX - Pure Stock Muscle Car Drag Race (FAST factory stock drag race)
Our first car is a 1970 1/2 Pontiac Tempest GT37, and the opponent is a 1970 AMC AMX 390. The Pontiac Tempest GT-37 was a very interesting car introduced in mid 1970. It was a cheaper option than the GTO, but had most of the GTO options available. If you opted for the largest engine, the 400ci, and also got a 4-speed manual transmission, then you automatically received the Ram Air III 400ci V8..... it just didn't have the Ram Air intake. Well, that’s according to some reports, which has been controversial over the years. I suspect it was the regular 400 featured in the GTO, but I don’t think it’s too outlandish to assume a few left the factory with the RAIII....it was the muscle car era, and you could get anything you wanted if you knew the right people. The automatic supposedly received the small valve 400 like that in the Catalina (CR was 10:1). Our featured car also has very aggressive 4.33 rear gears. The opponent is no slouch, and the AMX introduced in 1968 was a monster. Three different V8s were available with a 390 being the, "largest," even though all had the same external dimensions. Paired with a 4-speed manual transmission and 3.90 gears this car is a rocket! The AMC definitely has a weight advantage, so check out the video for more details.
