I watched a video last night of a guy driving around a '70 Duster with a basically stock 6.4 and 6-speed swapped in, he has to run drag radials on the street just so it won't spin the tires through the first 3 gears.
I also know a guy locally with a '72 Cuda who swapped a stock Hellcat engine back out for a healthy stroker SBM because it spun the tires so bad, he almost wrecked it on the freeway when he hit the gas and it did a 180, at 70 mph...
Yikes! I have daydreamed about stepping up to an HC in my '73 Duster after I have grown tired of the cammed 5.7 I am going to put in it. Not ready to give up on that but something to keep in mind.
He wasn't running 15" BFG's on it was he? :D
It sure would be cool to figure out how to retrofit traction control when swapping in a motor like that. I know in my lowly 5.7 Challenger TC might have saved me twice when the rear end suddenly stepped out on me, can't imagine what almost twice the HP and 800# less will be like.
Hotwire Auto's NAG1 kit uses the original ABS module to feed the TCM (among other things), and I am hoping to do something similar to feed a speed signal to the PCM so (maybe) I can get the factory CC working. Maybe by adding the other missing modules, perhaps TC could be added. In my mind the biggest hurdle after the wheel speed sensors is the steering wheel angle sensor. At that point, might be able to just plumb the ABS pump into the system and even have functioning ABS.
