I dug out my copy of the TSB dated 18 April 1966 on the D/Dart. These cars came to the dealers who ordered the as a 699 special order. This number was stamped on the fender tag. The engine code was 32. The LO23 showed on the broadcast sheet.

The only deleated option for the interior was rear seatbelts

All cars came with WW1 paint and interior trim was P4H red

The cam was a Racer Brown grind using Hemi tappets

The carb was installed using a special spacer to allow for full opening of the butterflys. The stock 273 4bl manifolds had small bore openings that would allow the 1 11/16 butterfly’s to open. A Holley 4160, List 3778 was used. I belive this was the carb used on the race Hemi. Someone may correct me on that.

Engine used a 318 truck crankshaft

It mention an over the counter offer of an Edelbrock duel 4 manifold as well as an Edelbrock single 4 manifold. I assume this is the LD4B.

Also mentions the use of the 392 Hemi intake valve. No mention of the pistons so I assume they may of been TRWs.
