If I knew what was in the car as far as a converter it would be different as far as what I would put in it. I would hate to drop it then only find out what I bought new is what's in there. This is my first automatic. My other mopars were 4 speeds, What mods are you talking about to the heads for springs ? If you are talking changing the springs I don't need to pull the heads to do that. The cam kit I had in my 440 RT I had to change the springs and I have the tools to change them on the car that's not a issue and I would rather change them as this motor in my Dart has never been apart it's all original as is the interior and all the sheet metal. The cam I had in my RT was from Straight Line Performance which is now Competition Components, the cam had Lobe lift .335 intake and .335 Exhaust, Valve lift was .503, Adv.Dur 270 In 284 EX,
