My buddy is just about finished putting a 5 speed in his 69 Dart. He is a perfectionist, anything he does is very well done. We call him Dr Dodge.
He's 79 years old and did all the work himself. He's an animal behind the wheel though. 408 535HP and still loves working on his car. He adjusts the valves once a week religiously and yes he's a Class "A" mechanic. Always been into Mopars.
