So my situation is I am trying to fix my dads 69 road runner. The wiring is 50 years old, he had it rebuilt 10 years ago but never drove it as he never had time. So on top of wiring gaskets all leak as they have dryer out. The motor has about 2000 miles on it. I took him for a ride in my ta this year and he loved it he loves power. He had a stroke and if he gets his license back would be great if the old bird had a little jamb to her. It is a four speed I believe they put the six barrel cam in it so a more aggressive cam would be okay but looking for a smooth idle. Hoping you Mopar guys could help me out. Will the 240 trickflow heads bolt on and make more power or is this just good advertising. Again not my car just wanna do something cool for my dad. Was also wondering about the Rack and pinion steering. Thought this might be move comfortably for him as he had a stroke and that finger steering leaves no feel for the road. Thanks guys
