I'd think you'd be just fine dropping a 351 into it with or without any smog control devices on it, the smog laws didn't start to get bad until around 1973-74 if I'm remembering correct.

Ca. doesn't even require cars made before 1974 to be smogged any longer, you could slap any old polluting gas burner you wanted into a 68 stang here in Ca.

I'd imagine Nevada would be even more open minded especially with a car that old.

Yeah I agree, why add the extra weight. I am pretty sure they did come with a smog pump.  I know the 69s had them

Quoted:
emission control devices were not required by law until 1973.

the only emission style items I recall on a motor that old would be a pcv value & a carbon canister the extra fuel(overflow) would flow threw on it way back to the tank

come on Muscle Car / Gear Heads anything else we're missing?

I don't know much about Fords, but my 1967 GTO had a smog pump as factory original equipment. Maybe it was just a CA requirement, but if original smog gear is required in your state, it could run into some big bucks.

Just read over my old service manuals and all california cars & manual transmission cars were equipped with a smog-pump.
