Anybody have a old Erson catalog so we can find out what the specs are on a BBC solid roller with R296-1 on it????

Here's what I came up with

Erson P/N 119802 chey 265-400 R2961

Advertized Duration Gross Lobe Valve
Duration @.050 Lift Separation Lash
296*IN 266*IN .600" IN 108 .032 IN
308*EX 278*EX .600"EX .032 EX

Well, I tried spacing it all out but that did'nt work. I'm sure you get the idea anyway.
