the Shelby's that i think that no ones knows about the 1986 Shelby GLHS Omni and 1987 charger GLHS. which stand for goes like heck some more. here are the specs:

The ‘1986 Shelby GLH-S’ was a modified Dodge Omni GLH, with changes made at the Shelby factory. They were retitled as Shelby Automobiles cars sold at select Dodge dealerships. GLH stood for “Goes Like Hell” and GLHS stood for Goes Like Hell S’more. Just 500 were made.

Dash plaques used a 3-digit serial numbering system (as only 500 were made).

The Turbo I engine was modified with pre-production pieces from what would become the Turbo II inline-four engine. These changes included an intercooler and other changes to produce 175 hp (130 kW) and a flat 175 ft·lbf (237 N·m) torque curve. Not included were any of the durability changes to the short block (forged crank, full floating pin, stouter connecting rods, etc.) of the 1987 Chrysler Turbo II engine. Luckily, the Shelby engines have proved to be reliable even without the durability enhancements of the production Turbo II. Performance was impressive, with just 6.5 s needed for 0–60 mph (97 km/h) and 14.8 s for the quarter mile (402 m) run. Top speed was 130 mph (209 km/h).
The 1987 Charger GLHS was based on the 1987 Shelby Charger. Shelby Automobiles purchased the last 1000 of these & they were shipped to the Whittier factory for modification. Shelby modified the Charger using the same pieces as the 1986 GLHS with some changes. These included a non EGR turbo, Shelby valve cover, wider Shelby windshield decal (no CS logos), different & more extensive tape graphics package, no reference to Dodge on the outer body, black/white speedo overlay, a 4-digit serial numbering system on the dash plaque, wider Mobil 1 plaque installed on the radiator support, & Centurian II wheels.

The 1987 Charger GLHS uses 1986 electronics & fault codes.

The dash plaque on 1987 GLHS Chargers read “Shelby Automobiles Inc”, “Carroll Shelby” autograph and “Charger GLH-S ####”.

Some early (low s/n) Charger GLHS’s came with a shortened 1986 GLHS windshield decal (CS logos removed).

All 1986 & 1987 GLHS’s were first run using conventional oil for engine break-in, then filled with Mobil 1 oil. All transaxles came filled with 5-30W engine oil.

All GLHSs came from Dodge in single stage black (no clearcoat).

There is at least one odd ball that was painted above the Shelby Factory strobe stripe by a dealership because the car wouldn’t sell making it a “Dealer option” much like the Yenko cars of the 60’s and 70’s. It’s almost hard to believe ‘Dealer options’ on those cars have added more than 10X the value over the factory production cars. The dealer had red paint added over the black. Because of their close proximity to the Whittier Shelby plant, Anaheim Dodge had at least six 87 GLHS’s on the lot at one time. They sold slowly and in October of 1988 they tried this repaint idea to move their very last unit. This vehicle is owned by the California Shelby Dodge Club president. All had the same options which included a leather-wrapped steering wheel and gearshift knob, air conditioning, sunroof, non-armrest center console and KONI struts/shocks on all four corners. There was also an allowance made for the 85 mph (140 km/h) speedometer in the form of a sticker which extended the range of the speedometer to an indicated 125 mph (200 km/h). By the time the speedometer had wrapped fully around to the “5 mph” mark, the car would have been going at 135 mph (217 km/h). There was also a new version of the Shelby “Centurion” wheel that looked very similar to the Centurion wheels on the 1986 Omni GLHS, but had the “blades” turning in the opposite direction. These are commonly known as Centurion II wheels.
