How to build a 13 second 340 Duster

My old Dart ran 13.18 @ 108.....stock 68 short block, grooved main bearings w/hi-volume pump, MP .484/284 cam and lifters, used Comp Cams steel retainers and springs, Mr. Gasket hardened keepers, LD340 w/3310-2 750 vac sec. with black spring. MP electronic ignition with chrome box and stock coil, Hooker 5204 1-3/4" headers w/2-1/2" pipes, DynoMax Super Turbos w/turndowns. GOOD Hays street/strip gold pressure plate and disc (could sidestep that thing all day long!), 3.23 gear, 6" X 27" J.C.Penny AFX Foremost cheater slicks. Carter electric fuel pump w/regulator and -8 fuel line to regulator. Car pulled like crazy, best times with trans left in third. Things that would have improved car: Change secondary spring to lighter one, Redone the trans with cut sliders, checked or changed to adjustable valvetrain.....the valves setted in two spots and the guides were wiped out. The combo was a blast to drive anywhere. The carb also had the secondary metering plate changed to allow jet changes. Simple combo, hope this helps! Bob
