Best E58 360HP Camshaft....your guesses

This may not be right but, my understanding is that the 68 manual trans 340 had a more aggressive cam then the automatic cars. Then the 69-73 340 had the 68 automatic cam. 74/75 360 hp engine has the 68 340 auto cam. Don’t know about the 76 360 darts/dusters. Kim

That's always been how I understood it too. And also that the 306 did use the 340 auto camshaft for at least one year....though I've seen people talk about it being used later.....I have no experience there so......
