Which cam grinder?
Call the ones you want to use and ask them
I'm going to have Bullett regrind a BB solid roller steel cam I have that has two damaged lobes, I ask them earlier this year about it and they said then about two weeks turn around time to get it back to me on regular ground shipping from MS or LA, which ever state they are in, back up here to central OR
I'm waiting on a local customer to decide if he wants the motor or not so I can make sure and get the compression ratio and camshaft grind correct for his needs
