I love that '68 Valiant! I had a '67 2 dr post that was originally a 273 Power Pack car with a 4 speed and a 3:91SG and stuck a '68 340 out of an early '68 Dart GTS in it and the only street car that ever beat it (by a fender) was a '67 Fairlaine 427 2 fours car. I'd love to see your car run. Good job!
