1970 RS-Z/28 for sale - Page 2

Am a bit out of my territory, but doesn't the '70 Z have a holley 780 cfm carburetor? Therefore, wouldn't the last letter on line 1 of the POP (if read frontwards) be an "H" not a "B"?

Standing by to be educated.....

Kind of a "tweener"......keep it as is or probably spend some serious bucks to get it up to a very nice driver status. Shouldn't the front grill be all black in color? Was there such a thing as a "Hurst package" as noted in the ad? How would that appear on a buildsheet? Is that the correct shifter & knob?

Anyone know what the white (black vinyl top) 70Z went for at the recent Mecum auction in IL?

Sam, Your correct. It should be a H. The 70 Z came with a 780 CFM Holley.

But:
Carburetor type: (H=Holley, R=Rochester,C=Carter, B=Bay City). Don't know what Bay City is.

There was no Hurst option. The shifter was a Hurst. I have a 1970 Order Guide and it shows these options only.

For a non console car the shifter ball is a 2 piece knob. Top is black with a white shift pattern and chrome bottom. For a console car the knob was chrome with no shift pattern. The shift pattern was on the console.

The shifter plate on the carpet should be black, not chrome.

Shouldnt the trim tag say Z28? or was that just Norwood cars?

Just Norwood Z's

and the grille question. The plastic that's square will only be black. The trim is chrome. The same goes for a non RS grille. The original grilles were black plastic all the way through. If you broke a piece off, you would see black and not silver. All grilles ordered from GM parts came silver and would need to be painted black for the Z28.

I'm learning here as well.....back to the carburetor, in looking at the add'l pix with this ad it shows a closeup of the carb and the numbers seem to be correct for a 780 cfm for that year/model/engine/trans. Are we sure about the protecto plate interpretation.....maybe the dealer simply put the wrong cfm wording in the ad?

COPO427 - should the vertical piece in the center of the grill be the same color as the car?

70 Z's were all 780 cfm secondary vacuum carbs. No double pumpers were used on the 70 Z28's. The list and part #'s are correct for a 4-spd 70 Z28. The ad is incorrect on the 850 DP.

The centre of the grille should be body coloured.
See this pic I took at a Camaro show. It's an original owner, original paint low mi 70 Z28. And before it's asked, the front spoiler wasn't available until 1971.

Just a note on the POP carb code. The 69 RS/SS I did up years ago was all numbers matching, etc. and the POP was correct except for the carb code. I actually sent a letter to Jerry McNeish with a copy of the POP and he essentially said he has record of an occasional error on those carb codes so it is not out of the question to have a mistake in that area.

**COPO** · #19 06-11-2005, 12:03 AM

Don, did the POP have the "A" "B" or "C" at the end of the trans code designating an M-20, 21, or 22? That is what I think is unusual about this particular POP.

Mark,

You are correct - unless the 1970 is COPO 9796 and mid June through August build.
