It's not nearly as bad as being blown. Once you been blown, you'll never want to do things the hard way again.

He asked me if it had a 3/4 cam in it. I had no idea what he was talking about. I didn't know if he was just phucking with me or what, so with a dead straight face I told him that we used the entire cam, not just 3/4's of it. He looked at me like I had 3 eyes and flippers and turned around and walked off. It was several years later before I found out what he was talking about. I honestly had no idea at that time. Guess it was a little before my time.

Bet you are kicking yourself now. My mom made my dad sell his BB split window Vette when I was born in 70. He sold it for $1800. Wish I had it now.
At the time, I literally had absolutely no idea what the guys was talking about. I found out later. So, there was only like 4 or 5 cam choices? Was there a 1/4 or 1/2 cam? |
What's a 3/4 Race Cam?
In the early 1950's the most popular original camshaft designers were the legendary Ed Winfield, the father of hotrodding, and Cliff Collins of Harman-Collins. If you look a Huntington's 1951 book you will find the specs for their cams listed. We've also listed some of their cams on our Flathead Performance Cams page. There were lots of cam grinders that copied Winfield and Harman-Collins cams, but these two were the designers and innovators in the early days. It was popular to refer to cams as a 1/2 Race or Semi grind and a Full Race grind. Later, there was a call for an intermediate grind between these two. To fill this demand, Ed Winfield took the intake lobe from his full race cam and the exhaust lobe from his semi cam and called it a 3/4 Race cam (see Flathead Performance Cams). It was literally half way between a full race and 1/2 race cam. Since that time, 3/4 Race has become a generic term for a high performance street cam, i.e. something less than a race cam. |

Thats a very cool find MT. It just goes to show that alot of those weird sayings actually did come from logic of their day.
