I have been out of the Loop for some time. In 87' I bought a Purple Direct Connection cam from them with the 68' manual specs to go into my 69' 4-speed Dart Swinger that I still have (see photo). I also have a DC cam (auto specs) in my Van. Both run well. Hard to compare, due to the apps. Just last year I tossed a good Crain cam "Fireball" cam that I had sitting around 35 years. My Bad!!!!
