ENGINE BAY RESTORATION COMPLETED APRIL 21, 2007
I wanted to keep the engine bay as close to stock appearing as possible, down to the smallest detail, while a... Show moret same time introducing a few necessary modifications to increase performance and/or improve the overall appearance. For example I did not re-install the factory air conditioning system (compressor, condensor, hoses, etc.)
This is the original date-coded alternator attached to a factory "air-conditioning delete" bracket. You can also see the correct NOS oil filter, part number 04419970. This oil filter was unique and used only on the 1986 and 1987 GLHS cars. Many bolts received zinc phoshate coating to duplicate a correct new bolt. Note the NOS alternator belt, complete with correct Mopar part number markings.
The top of fan shroud received a reproduction "fan warning" decal, since an NOS decal wasnt available.
The nut/washers seen here on the strut towers received yellow cadmium finishing, which was correct for these cars. Also you can see an NOS overflow bottle and cap.
The original electrical solenoids were refinished in clear cadmium to duplicate a new part.
All the original wiring was cleaned and re-wrapped in correct friction tape. If you look closely you can see another modification which is the use of a "grainger valve" to manually control the boost (it's the brass valve installed just below the bank of 4 vacuum solenoids). Note that the original horn has been restored, as well as the original coil bracket. This car even has both of the original 1986 date-coded Wagner headlights. Note the restored headlight wiring.
The headlights were manufactured in 1986 and still work.
The correct friction-tape and conduit wrapping configuration for the front lower wiring was duplicated in the restoration. The correct NOS clips were installed to attach the wiring to various underhood components.
Correctly finished NOS hood latch and original spring, along with a reproduction emissions decal on the radiator support.
And one more modification was the addition of a blow off valve seen here in the lower intercooler hose (this location helps hide the valve). NOS correct upper and lower radiator hoses were used. You can also see the Super 60 intercooler which is visually identical to the original intercooler.
Here you see an NOS valve cover sticker. The oil cap is the correct type, but the "CS" medallion in the center of the cap is an aftermarket piece that I chose to use because it just really looks better. The valve cover is the correct part, and is finished in the correct silver color (powder coated instead of painted like Dodge did).
One item that was not restored was the original build tag seen here in the lower center of this picture, attached to the radiator support. This tag still retains the original paint applied in 1986. I deliberately wanted to keep this "fossil" intact for reference purposes.
MORE PIX OF ENGINE BAY RESTO TAKEN JUNE 2007:
Front plate says it all.
Cylinder head was re-finished in natural cast aluminum and block refinished in correct high gloss black. Turbocharger coolant and oil feed hoses are all original pieces, refinished to new specs.
Deleting the air conditioning compressor and related plumbing really opens up the engine bay and deleting the a/c condensor frees up airflow to the intercooler.
The intercooler can be seen behind the grill just to the left (as viewed) of the driver's-side headlight. The air conditioning condensor (had it been re-installed) would have blocked airflow to the intercooler. In my opinion, it was a mistake for Shelby to make these cars with air conditioning.
Battery is a genuine Mopar replacement but is slightly different in appearance than the 1986 battery (forget about finding one of those). Battery cables and terminals are all restored to correct appearance.
Note the correct evaporation canister ejection hose, black w/ red rectangles and ribs on the hose. All the original vacuum hoses are restored to new specs.
It's no 426 Hemi engine bay, afterall it's just an Omni.
Rick kindly donated a set of NOS vacuum solenoid filters which help complete the correct factory look of the solenoids.
July 21, 2007, Larz Auto Museum's American Musclecar Show, Boston, MA. The car was awarded "Best Numbered Shelby". Same show, here you can see the person I purchased the car from, Paul Z., who was the car's second owner. Show Less
