Ditto on that Dave. The language started to change when the engines came out with OHV's. When I built the 32 5/W coupe back in 1958 I used a Duntov ( Fi ) cam , solid lifters, 4bbl, and aluminum fly wheel. You know the car ran good with just the minor changes.

The term 3/4 and full was used more with my flat head friends.
