When you know you are not dealing with a mopar person
For those interested, Ed Winfield was the "father" of the 1/2, 3/4 and full race cams. Read here.
What's a 3/4 Race Cam?
Several companies picked up on the 3/4 cam marketing idea and made cams they marketed as 3/4 cams. Alliance was one. I had one in a 350 Chevy in a Nova a long time ago. I even remember the specs. .480/292 on a 107. It sounded really good through two Thrush beer can header mufflers........and nuthin else. lol Alliance was just one company. Clay Smith Cams was another. I think they still make their version.
