1970 DCE GTO. For those that aren't hardcore Pontiac enthusiasts, option W73, DCE stands for "Driver Controlled Exhaust"...otherwise known as VOE, "Vacuum Operated Exhaust". 

This option was available for less than 2 months when the big wigs at Pontiac saw the Superbowl ad and cancelled the option.

It was similar to the Ram Air option, but it was much more rare and more effective. It had the bracket under the dash with an exhaust sticker rather than a ram air sticker. Once the knob was pulled, built up vacuum would activate the actuators on special mufflers moving the rod inside which would open and close chambers in the mufflers. Opening the chambers would let the exhaust flow straight through. What upset the big wigs was that the exhaust note was alot LOUDER. Check out the original commercial on you tube...just type in VOE GTO superbowl commercial.

There were 233 W73 GTO's made and this is one of 54 automatic hartops documented by GM of Canada. It has the original NUMBERS MATCHING block and 13 Heads with edelbrock intake and holley carb and headers. I have an original dated 068 intake and original dated quadrajet and manifolds. The car has alot of the original parts for the DCE setup and about 2 years ago I purchased the remainder of the parts needed to have the setup operational again, including the mufflers. I bought the car with 89000 miles and after 18 years it has less than 6000 more miles. Because I've hardly driven the car and never had it apart I don't know if the tranny is original and at some point someone installed a 12 Bolt rear end.

The car is a bronze colour right now with the original sandalwood interior. The original colour was Sierra Yellow. Here are the rest of the options:

AK1   Deluxe seat belts and shoulder harness

AO2   Glass - Tinted windshield

A39   Frt & RR Seat belts - Deluxe

A85   Frt Seat Shldr Harness Deluxe

D33   Outside Rear View Mirror - LH - Remote Control

NK3   Steering Wheel Sport, Soft rim Sim. Leather

N33   Steering Wheel - Tilt - Type

N41   Steering PWR ( variable ratio )

U63   Radio - Pushbutton

VK1   Plate, FRT LIC MT PKG

W63   Rally Gauge & Clock

W73   Driver Controlled Exhaust

The car runs but the mufflers are blown... I was going to put the complete DCE system on but then wanted to wait untill the car was restored so that it would be fresh.  Floors and Frame are solid. Car has a couple of bubbles at the bottom of fenders doors and quarters. Trunk pan has some rust where it meets the inner wheel house so it might need to be replaced or patched. Rear bumper has started to pit. Rear spoiler is an original GM spoiler put on by a previous owner many years ago.

Great car overall with everything there.
