On the other hand, stainless steel headers will not rust or corrode but cost more up front. The Grant GT steering wheel is mounted to a tilting column, and white-dial Dolphin instrumentation consists of a 140-mph speedometer, an 8k-rpm tachometer, and auxiliary gauges. Like the Camaro, the 1990 Firebird only received a half-year production run, as Pontiac labored to release the restyled 1991 model.

To provide clearance for that long-stroke, engineers modified both the block and the connecting rods. Four-bolt main caps and a forged rotating assembly assure strength and durability. During development, a single engine endured more than 200 simulated drag strip passes on a dynamometer. From 1991, the 454 was updated to the new Gen V block, crankshaft and heads.

Available in two lengths and includes individual baffle inserts for each tube. Included below is a chart showing the dimensions commonly used for header measurement when checking for fitment, especially with universal fit headers. Here at Speedway Motors we list these dimensions on each product page, and you can narrow your search results by them as well. Chrome plating is another header coating option you may consider, however it is typically suggested for a show car type of application only.

Ceramic coating will not only reduce corrosion but it also adds a thermal barrier which will reduce the under-hood temperatures. It is an excellent option to consider when you are using mild steel headers. Ceramic coating goes by many brand names and here at Speedway Motors ours is called AHC which stands for Armor Hot Coat.

Gold 16-inch, flat-mesh, diamond-spoke wheels were standard on GTA, with 16-inch, 20-slot wheels standard on Trans Am. The Trans Am’s basic layout was very similar to the earlier 1983 Trans Am, except they were now available with the optional RPO W62 ground effects package, previously used on the 1983 Daytona Pace Car Edition. Another new for 1984 option was the “High-Tech” 15-inch, 20-slot, concave aluminum wheels, painted gold or silver, with black plastic centercaps containing a gold or silver Firebird logo. L69-equipped Trans Ams also received an 8,000 RPM tachometer, an 80 PSI oil pressure gauge, a high-output single electric fan, a functional cold-air induction hood, a higher output mechanical fuel pump, and a secondary electric fuel pump to help prevent vapor lock. The Trans Am came standard with a new incarnation of its traditional “Air Extractors” on the fenders.

We can make it in the tube size you need, in a stepped or non-stepped configuration, and with all the customizations you could ever want. These are designed to fit the Classic Small Block Chevrolet engine 1955 and up. Two styles are available for spark plug clearance on standard and angle plug heads. GPHeaders’ Small Block Chevy Header Mockup Kit allows you to design a set of truly custom headers without the vehicle ever leaving your location. We supply our customers with mockup header flanges and collectors along with our adjustable aluminum mockup elbows allowing you to design any header imaginable.

The custom interior is trimmed in red and white vinyl and outfitted with a Lokar shifter, tilt steering column, and Dolphin instrumentation. This customized ’39 Ford is now offered with a clean Texas title in the seller’s name. The Firebird remained basically unchanged from the previous model year. All automatic transmission Firebirds now received a T-handle shifter knob, and the shift indicator changed for the Automatic Overdrive 700-R4. Midyear, the L69 high output 305 cubic inch engine was introduced. In all forms (except the aluminum ZL-1), the Mark IV was slightly heavier than the W-series model, with a dry weight of about 685&nbsp
