Sig Erson Was Good Stuff !
Used em in the 70’s .

Could ; TQ signify a Torque Priority Cam ?
Could ; 111 Signify Overlap ?

Suggestion; IF you’re in the build process have it “ degreed “ in your block & see what
The engine builder reports !

My 2 cents ….

From the 1999 Erson Catalog:

A Engine, part number E420121, Grind TQ20H:

B Engine, part number E410121, Grind TQ20H:

could be it?

I don’t have it in my hands so I can’t measure base circle and lobes to see if those are close. Tq20h is promising. I wonder those if the 111682 should be part of the equation?

Permission to speak freely?
Sounds like a shitty old grind. Small lift, small duration @ 50, huge adv duration... a recipe for a poor performer that sounds rough.

It’s a streeter …..

Little hotter than stock , probably utilizing stock springs , pushrods & rockers …

Fairly inexpensive too ….

All depends on what are you’re goals for the engine & what the budget is !

I agree, it looks like a shitty old grind so far, and I have no plans to use it. It was available used with matching lifters for cheap so I thought if it was descent, read something with another 60-70 thou lift and 30 more duration I’d buy it as the metallurgy would be way better than the butter cams of today.


Thanks all for the input
