In the latest episode of Generation Gap, Matt and Davin have brought the muscle. Matt’s pick, a 1987 Buick GNX, is arguably one of the best muscle cars to come out of the 1980s, with a McLaren Performance-tuned turbo-charged V-6 putting 245 hp and 360 ft.-lb. of torque to the ground. Davin thought he could slip one by with this unassuming 1969 Chevrolet Chevelle. The secret is that it’s a rare COPO with the 427-cid engine with 425 hp and 460 ft.-lb. of torque. This Chevelle looks like grandma’s car, but goes like a Yenko.
