A few of the camping forum guys recommend getting the smog crap off the engine. But, they don't get
specific enough.

You mean, break the law?

"Take the smog crap off" worked in the 70s when emission control was a
clumsy add on to a conventional engine. These days the computer is
your smog control. You can certainly tune the computer for more power
and less for economy but the most efficient burn will usually also
give you the least emissions. I bet a new NASCAR racer would pass the
1975 emission controls at anything but idle speed. Fuel consumption is
important to them too.

No way... It's important but there is no way they get that good of a
burn without a catalytic converter...

They sure will! They've been completely engineered to operate as
efficiently as possible from conception on up, without a need for a
catalytic converter.

Need or not, they wouldn't run a cat... These are race cars. I still
don't buy them passing emissions now. I know how fuel moves through an
engine, I don't care how many computers you have. Heads are heads,
valves are valves, and pistons are still pistons...

What you are not understanding is that the OP said that the NASCAR
engines would pass *1975* era emissions requirements, and I'll bet
that's true.
