Curious
I think the question the OP is asking is pretty straightforward. Getting the 1/4 mile number to beat an LS Camaro is relatively easy. The highway MPG - not so much. He is running a '69 Dart with a 727 - 4:10 and 29" tall tires. The engine combo is a basic tried and true 496 stroker. Edelbrock RPM's out of the box, 10.5 compression pump gas friendly, Lunati big hydraulic cam, headers, Edelbrock Super Victor and a 1050 Dominator. Car runs 10.90's all day long. With a small dose of Nawss, it runs 10.20's. LS slayer....
