Zenith 32 NDIX carbs are correct for 1960 model year 1600S (616/2) engines, which start in the high 84,000s.

My 59 1600Super has original Zenith 32 NDIX carbs. All the factory books I have state Zenith for late T2 "A" super models. They have different size jets to the normal engined "A"'s.

Zenith 32NDIX carbs were installed on 356A normal and Super motors After Sept 1957. Starting with Engine number 67001 for normals and engine number 80201 for Supers. They replaced single barrel Solex carbs (32PBIC on normals and 40PICB on Supers). Your engine is a 1960 356B Super engine. It was made in 1959, though. It would have come with Zenith carbs. Super 90 engines followed soon after and were equipped with Solex 40P11 carbs. Zenith carbs do have different jetting depending whether they were Normals or Supers. The bigger difference, though, is the size of the venturis. Normals have 24mm venturis and Supers and 356Cs have 28mm venturis. TMI?

And in all engine with Zeniths, the Normals came with inlet manifolds with smaller openings at the intake valves than the Supers. In the case of a Normal manifold on a Super engine, you could carefully grind the manifold open a bit to match the head, but going the other way you need to grind on the heads. Best to get the proper manifold for your heads.

If you just buy a set of Zeniths "with manifolds" you may not know what you're getting even if the seller thinks he knows.

Slight correction. All the Normals and Supers had the same port size when using the Zeniths. The C had the larger ports, and is the only Zenith manifold that is bigger at the head.

Vic,

More than a "slight correction!" :shock:

I defer to you, of course, but I have a chart somewhere (Pellow's "Little Spec Book"?) showing a slight difference between Normal and Super, and a major difference with the C. Can't pull it up now as I am in the office.

Suffice to say: Check for correct part when sourcing used Zenith manifolds.

Thanks as always for the oversight.

Vic is correct! The only "different" manifold for Zenith carbs is the C manifold. You may be confusing intake ports with intake manifolds.

I stand rebuked. But if the Normal vs Super intake valves are different, shouldn't the inlet openings be different, however slightly?

Intake valves were the same. The only different ones were the 40mm S-90.

Zeniths were the carb for the 1600S. The cars ran quite well on them. My test dyno motor,The Mule, generates 84 hp with the 1600S set up. I just tested a Pete Weber free flow exhaust with the same set and it did 92 hp! These were test for the Peking?Paris motor.

Large Solex's an extractor exhaust AND a pre-A crank pulley? That's a strange combo going there.

I have Zenith 32's on my 1959 1600 Super. The carbs and engine are in pieces ready to be restored, but I have them! :wink:

I keep staring at that pulley too, wondering how it seals since that type cannot be installed with the crankshaft seal in place. Wrong ratio for the upper pulley as well. The fuel pump top is installed backwards, making fuel lines impossible to install. I'm sure the coil will interfere with the free movement of the throttle linkage. Maybe that's why they don't need throttle return springs and the associated brackets. And the Porsche style dust cover/strap on the VW generator. I didn't think that those pieces fit together. I wonder if the internals were assembled by the same person? :?

Ok, I'll let Harry Pellow (RIP) take the hit on this one. As I recalled, his "Little Spec Book" lists Zenith manifold port sizes :


Normal: 1.17" x 1.37"
Super: 1.2" x 1.4"
C/SC: 1.4" x 1.6"

Yes, I roll me eyes now, too, as a Normal and Super are essentially the same when rounded off to the nearest tenth . It's curious why he chose to add the extra fraction of a tenth for the Normal. He either thought he could measure the difference repeatably, or his factory sources were being quoted faithfully. My guess is he measured them that way.
