It stands for "with clean air package". I think it was for California.

Alan,
Good hunting there. Headers in trunk, just like the 67 R/O Plymouth and
67 W/O Dodge race packages. Always had a question about those
Doug Headers with the smaller collector sizes. NHRA limited collector sizes, they could not exceed the size of the largest diameter of the exhaust system (I think 2 3/4" was the opening in that large "Y" pipe) or a tad smaller. For stock classes, Super Stock could have openings up to
3 1/2".
The cast iron intakes with the 1 11/16" openings for primary and secondary were found on marine applications, as they all pretty much utilized Holley carburetors. Dig up Chrysler Marine info, you'll find a bunch of stuff. They were really leaps and bounds ahead of the small-block drag race guys at Chrysler. In 68', many of the 318 marine engines had the larger-bore cast iron intakes on the engines, and better camshafts, thanks to Camcraft, out of Easton, Maryland.
Paul, (Bigger valve size, that one I have got to look into. As for the
shifter, I think it was a 1966 safety issue. Requiring a positive lock-out on the reverse gear and/or indicator on all cars, Protecting the factory from liability claims.)

Alan,
The D-Dart mysteries makes your head spin.
Kind of like a 16 year-old virgin on a carousel, at a prison rodeo.
The D-Dart carb spacer part #2863052 (.938 thickness).
The intake (free-flowing/modified intake) may have been an earlier version, similar to, Vanke's intake modifications on the 67' R/O and W/O Hemi Super/Stock manifolds.
One things for sure, all small-block 273 Mopar guys were cutting out the center shut-out areas on the intakes, for increased air-flow at top-end, back then. As well as putting on a 15/16"-thick heat-risers between the carb. and intake, to prevent vapor lock.

Wonderful research, thanks for the in-depth info, keep it coming!

Thanks,

Paul,
You come up with some great quote.........................Lov'em

The spacer that came on the D/Darts was a 1/2" aluminum plate. It was an in-house, crudely machined part. Not sure what the over-the-counter part (2863052 - carb flange) dimensions are. But, the price was $18.95.

I popped open the throttle plates on "The Pollitician" a little while ago. It has the 4 holes in the intake. I'm sure if it ment picking up a few ponies, Ted Spehar or Al Adam would have cut out the center.

Sent out a couple of emails looking for info on the Hurst shifter. In the SS&DI article on "The Pollitician", there's a shot of the interior with a thin, round handled Hurst shifter. It might be the one that your talking about. It's also seen on the D/Dart campaigned by Coronet Dodge.

Alan,
On the Hurst shifter. Still tracking info. Stuck on part #3916790, But that comes up for a 66'-69' B-Body. I wonder if that was also used for the
D-Dart. It came through with a long-handle shifter (16", I think). Now the
65' Darts (273/235HP Commando's) came through with the Hurst shifter
as standard equipment. Wondering, if they utilized that shifter with the
D-Dart?? As I said earlier, the Inland shifter (for 66', 67' and early 68')
Mopars had to be installed in the cars for safety reasons (positive
reverse lock-out mechanism). After they got to the dealers, than the options were installed (ie; Doug Headers).
As for the intake, I'm wondering if there were (2) different versions. The
66' 273 marine engines and early "LA" 318 marine engines had a modified intake with the center shut-out area removed. I know that for a fact, because at my fathers engine shop we had several 273/318 marine engines come in with factory installed Holley carbs on the intake, not sure of cfm size, maybe 600's or 650's. The adapters were aluminum, and had 4-tapered holes (funnel-type), mounted on the open-throat intake.

Paul,

Buddy of mine has one of those marine intakes with the 1 11/16" bores at the last swap meet we wereselling at. I almost fell over myself when I saw the intake unloaded and that he was selling it. First thing that caught my eye was those large bores and I thought I had scored. Disappointed when I checked the part number.
