I purchased a 69 Z/28 in 1976. It had been rode hard and put up wet. Aftermarket ignition,
intake and exhaust etc. I knew I would want to put it back stock someday so I purchased a bunch
of parts in 1978. This manifold was among those parts. Of course, not knowing the correct
casting numbers, I had no idea that this was “correct” for the 1970, 71 Z , Corvette LT1, and
Yenko Duece COPO vehicles.

Anyway, I kept this in the box until it was installed on a DZ motor in about 1986. I drove the car
at most 200 miles. It mostly sat waiting for me to get to that restoration. I disassembled the
motor in 1997. Other than to shoot it with a little carb cleaner to get the fingerprints off, this
manifold has not been cleaned in any way. No sand blast, no bead blast, no dipping etc. It is
nearly perfect. You can see just a slight bit of rust deposit around the bolt holes. These can be
cleaned up, but I wanted everyone to see just how clean this manifold was just as I removed it
eight years ago. You can even see a little purplish fuel deposit if you look down the plenum area.
Divider has not been touched in any way. Only the factory machine marks. Winters logo is very
clear. Never been polished an any way. What appears to be a crack across on runner is simply
the factory casting flash. You will be hard pressed to find a better looking intake, even if it is
still in the box.

There is one tiny imperfection. Up front just left of the factory freeze plug, there is a small hole
about 18 inch in diameter. Not sure what is up with that, but it can be easily fixed cosmetically
and will not be in a conspicuous place.

Absolutely no repaired threads. All mating surfaces are PERFECT. Even the heat shield is
perfect. Not even any flash rust. I have no idea what the casting date is, and I am not about to
remove the heat shield to find out, so please don’t ask.

Shipping will be a flat $20 to continental U.S. business address, $25 to a residence.

Lynn, the deuces used the 2110 70 LT1 intake. A one year only intake #.

Thanks. Sorry about that. I thought they used the LT1 engine same as Z/28 and Corvettes. Learn something new every day here.

116 intake was only "over the counter", not factory installed on anything. $350.00 is just a bit optimistic.

Lynn, the deuces do have the same LT1 as the Z28, they just have the 2110 intake per the factory, not the 2116 version. Nice lookin intake though.

(didn't the 2116 come on the '71 Z28's??)

Mikes Nasty Z site shows the different 70~71~72 Z-28 / LT-1 engine pieces.

I take issue, John. $350 is more than a "bit" optimistic, it is WAY optimistic for an over the counter part. Although I guess I could put it on ebay and claim it is an "over the counter high performance part just like a cross ram".

I feel like a real dumb sh!t. I bought my first 69 Z/28 in 1971, and have been around lots of muscle cars since then (obviously not many 2nd gen Z's) and for years thought I had a 1970 intake. Did not know it was strictly over the counter, which makes sense, since that is how I acquired it! Will update the ad on camaros.net.

I will probably just keep it. It is in such good condition and looks better than my 472 intake, so I may even put it on my car or just save it for another project. Guess it would work well for someone doing a "day two" job on a SS 350.

This would have been much more entertaining if some dishonest guy had listed it as having been removed on day 2 from a brand new 70 LT1 engine. Don't you love some of the BS stories you get with parts for sale?

Thanks for the education guys.

Still a very nice lookin intake, an excellent performance part too.

Marlin,

Accoriding to the nastyz site, the 71 also had the 3972110 intake.

Most 71s I've seen have the 9594 intake with the cyl #s cast on the runners. 71 LT1s also changed head castings. I could see it being possible for early 71s to get the 2110s.I've found in this hobby there are very few absolutes.
