How do you know it’s a real Hurst/Olds? Well, this page is set up to illustrate the unique features of the 83 and 84 Hurst/Olds that are the more difficult ones to ‘just bolt on” so you can be sure the H/O you are purchasing is the real-deal and not just a Cutlass with a cool paint job! Granted any one of these items could be installed on any G-body Cutlass, however it’s not likely that the average person would go to such lengths.
Only the 83-87 H/O and 442 had this unique exhaust. Look for the dents in the corners of the mufflers and the welded tailpipes on low-mile original cars. On all W40 (H/O) and W42(442) cars there are specific heat shields near the tail pipes that single exhaust cars don’t have. See Shop manual pic on this page for addition info.

Only 1984 and newer GM vehicles had this sticker inside the trunk lid. So, on the ’84 look for W40 and look for 9 as the 8th digit of the VIN on either year vehicle.
Look for the indentation on the upper door panel where the Calais logo would go if it were not an H/O
Only the 83-84 H/O and 85-87 442 had this wide-open throttle AC cut out switch.
Look for 83553 or 84553 in the carburetor number on the cable/linkage side of the carburetor.
Although this is technically a bolt on piece on an ’83, look for W40 and any signs of removal/reinstallation.
Only the H/O had the heavier trunk springs with pink ends.
This page is out of the ’83 Shop Manual showing the positioning of the exhaust and heat shields unique to the H/O.
Look for this yellow tag on an ’84 transmission or a light the blue tag on an ’83 showing “OZ” indicating the specially tuned 200-4R with higher shift points and a 2400 rpm stall speed torque converter.
This is the tag from an ’83 Hurst/Olds.
