Erson Cam catalog

Anybody got a old catalog? I'm trying to find all of the specs on a BBC solid roller cam from what I remember 680 intake, 680 exhaust, 108 centerline, something in the notes "easy on parts"??? Thanks..

 

Got one from about 1980, is that old enough? I'll check it when I get home tonight.

 

I think so.... thanks.

 

How long has erson been around??? and how old is my erson gear drive timing cover??

 

Oops, forgot when I got home. Sorry, I'll write myself a note.


"Sig" Erson cams has been around a LONG time, I've seen adds for them in some of my 50's magazines.
