Sig Erson Cam Question
Our 1970 442 W-30 has a Sig Erson Cam in it The profile is the old Hi Flow 2H with a part #540541. The cam has only been in the car for break in and with the car in Calif, I am trying to decide if I should keep the cam or replace it once I get it here in Ohio. I don't know much about the cam though.
Is it worth keeping or should I look at changing it out when I refresh the rest of the car?

I found the cam card, so here is the information from it.
Valve Lift on both intake and exhaust is .504
Duration on both is 306*
Duration at .050 on both is 235*
Lobe Separation is 108*
Having found the card this am, Is it still worth keeping?
