1970 Dodge Demon 340 vs 1970 Chevrolet Camaro SS396 L78. Pure Stock Drag Race (factory stock drag racing)
Our first car is a monster! A 1970 Dodge Demon 340 (the evil twin of the Plymouth Duster 340). The other car might look like a Z28, but it's actually a 1970 Chevy Camaro Super Sport 396 with a L78 with 375 horsepower! The Demon 340 was rather rare that year with only 10,000 made. However, the Camaro SS is even more rare with only 600 (!) L78s produced in 1970. For comparison, they made over 10 times more Z28s in 1970! If you're a fan of watching muscle cars drag race, well, this is a good match for you!

Remember, both cars participate in Factory Stock class through F.A.S.T drag racing. Make sure you visit their website. https://www.fastdrags.com
