In the process of dismantling my 308, I found a Sig Erson Camshaft with the following markings HI-R H1. It also has E77 10 106 B. Does anyone know the specs of this cam? I know that Sig Erson made some legendary cams for the 308 - TQ20, TQ30 and a combination of both.
I would be grateful for any knowledge on these.
Cheers Steve
