Anyone running catalytic converters on car with flat tappet cam?

Not really buying all that. I think the "Zinc Danger" is way overblown like a lot of other Gov't BS.

Yeah, the gov't went and used their voodoo to control chemistry just to screw with you. :realcrazy:

It's really no wonder there's a lack of quality technical posts here. Engineering, science, chemistry.. it's all just goobermint and snake oil salesmen. I guess everything really did peak in 1969 and it's all been BS since.
