I believe in 1969 they did, so I would think they did in 70. Good question....

Yes, would have had smog installed.. All 70 solid lifter cars had it as well irregardless of whether or not stick or auto trans... Bizarre thing is that to my knowledge, 70 Chevelle 350 horse cars did not get it whether it was a stick or auto trans.. But in 69 a 350 horse stick car would have had it. I can't understand that one..

Of course, west coast delivered cars are different I believe..

All big block Novas did have smog in '69. I helped my buddy who bought a new '69 Nova SS 375 HP with M40 trans take it off when the car was three weeks old.

Bill Hodel from OH can also confirm this.

Merry Christmas,

All 1970 cars had the new TCS system...I believe this eliminated the need for the smog on non-solid lifter motors(except for CA) Our 70 Canadian L78 has the original smog system on it.....

Tom, I forgot about the new 70 TCS systems which makes sense why they could have got away with not putting the air pumps on the non solid lifter 70 performance cars...
