Laugh all you want, it's all true no BS. It's all in getting the right combination. Race all season testing. Started out with 4 speed 12.40 down to 12.14 but kept braking parts axle, ring and pinion, So went to auto 727 ran 12.04 change convertor 11.94 change trans to 904 ran 11.79 got it down...
1972 Duster
70 340 30 over TRW 10.5 pistons, stock rods and crank, X heads Just a very little bowl work, stock valves, solid 528 cam Victor 340 intake, 750 carb, 904 trans, 8 3/4 430 gears, 002 003 springs snubber, ran 11.62 at 116mph
so if you bought your car new and had the dealer install the ld340 before deliver your factory car came with it?? Its a mopar accessory so why could it not come on it new. Its like adding on factory mud flap. This is all BS
We have a 1970 Duster 340 stick car with stock stroke at are track running low 9s. I think he just went to a 350 something stroke, He's owned the car since new and it is a real 340 stick car.
