i would just do it and ignore those that says its wrong, most fast mopar cars are not realy all that much mopar anyway,they are more indy,edelbrock,holley,hooker,eagle,scat,mark williams, diamond,rci, bds,weiand and or any other brand, leave that boring my car is mopar or no car for the stock restauraiton guys, for me the guys how feel diferent can keep on playing with those j heads and stock converters and see where the limit is..
