Upgraded 400/4-Speed: 1979 Pontiac Firebird

It is no secret that by the end of the 1970s, high-performance models lacked that one attribute required to wear that tag…power. Vehicles that had been able to transform tires into smoke at the decade’s start struggled to produce a squeak when the driver dropped the clutch in anger. The 1979 Pontiac Firebird was no exception, although the seller has spent the time and money to give this beauty the performance credentials it deserves. The upgraded V8 would allow the buyer to relive the glory days in a car that presents well as a driver-grade classic. A new home is beckoning, with the seller listing the Firebird here on Craigslist in Billings, Montana. They set their price at $14,990, and I must say a big thank you to Barn Finder Tony P for spotting this potent Pontiac.

Assessing the overall condition of this Firebird is challenging due to the low-quality images provided in the listing. However, the seller admits the Code 50 Gold paint has seen better days and that a cosmetic refresh will probably be on the buyer’s agenda. They will be commencing that project from a sound base because the panels are free from significant defects, and the car is claimed to be rust-free. An in-person inspection is always advisable to confirm that prone areas like the rear valance and trunk pan are solid, but first impressions are positive. The hood features the iconic Screaming Chicken that is a hallmark of a Trans Am, and whether this is replaced following the repaint will be at the buyer’s discretion. Some may opt to transform the Firebird into a Trans Am tribute, while others might prefer the sleeper look. The plastic and glass are in good order, with the Pontiac rolling on a tidy set of Rally II wheels with color-matched inserts.

This classic’s exterior might be subtle, restrained, and needing love, but it is a different story below the surface. Buyers could order a ’79 Firebird with a 400ci V8 under the hood that delivered 220hp and 320 ft/lbs of torque. This was only available matched to a four-speed manual transmission, allowing the car to cover the ¼-mile in 16 seconds. That figure was considered respectable during that era, especially when a Mustang Cobra took 16.5 seconds to complete the same journey, and the Camaro Z28 brought up the tail in 16.7 seconds. However, the seller has spent the cash to render those figures irrelevant. This car rolled off the line with the asthmatic 301ci powerplant under the hood, but it appears it has been consigned to boat anchor duties. Its spot now houses a 400ci engine of 1970 vintage. The cylinder heads are dated 1969, while the engine block received a 0.030″ overbore and an Isky camshaft during a rebuild. It inhales deeply through an Edelbrock carburetor, and the seller says it now sends 400hp to the rear wheels via a four-speed manual transmission. Forget a 16-second ET because a sub-14-second pass should be comfortably within this Firebird’s reach. The buyer won’t need to spend a dime on this car’s drivetrain because it is in excellent mechanical health. It runs and drives well and is a turnkey proposition.

While the Firebird’s drivetrain won’t need a penny spent on it, the news could be less favorable with its interior. The vinyl upholstered surfaces look good, with no wear or physical damage. The console and most plastic components haven’t succumbed to age or UV damage, but the carpet is quite stained. A replacement carpet set retails for around $220, and fitting this would make a significant difference. However, the dashpad is cracked, and it may be beyond repair. A simple $50 cover would hide the issue, which could be the approach adopted by a new owner on a tight budget. The next step up the ladder would be a molded topper for $150. The quality of these has improved enormously over the last few years, and it can be challenging to recognize one after installation. The top rung would be to replace the pad, but this will lighten the buyer’s wallet by around $1,100. A perfectionist might choose that option, and while it isn’t cheap, it should represent a one-off expense. The Firebird features a sports gauge cluster and air conditioning, with a modern CD player occupying the spot formerly reserved for the factory radio.

Slipping behind the wheel of this 1979 Firebird would provide a driving experience that buyers could only imagine that year. It has power to burn, and addressing most of the remaining shortcomings would be straightforward and pretty affordable. Placing a value on a vehicle of this type is difficult because a modified car is only worth what someone is willing to pay. However, its rust-free state and engine upgrade could make it irresistible to some. That is why I believe finding a new home won’t take long. Do you agree?

    Very nice Firebird, and it probably wouldn’t take a lot to make it even nicer. I’d buy it, have it repainted, and freshen the interior.

      Fully agree. I had a 79 TA with a very well massaged 400 under the hood and factory 4 speed. GOBS of torque and a whole lot of fun. I like the color of this one. But the decal on the hood doesn’t suit the car.

    Together they make their way across the unknown & encounter the unexpected all the while a Cop who’d been imprisoned in Thailand attempts to hunt them down & inadvertently rescues them using deadly martial arts.
    Wayne himself is no slouch he carries a Hammer which he uses to met out Justice as he sees fit in a world of crooks & bad guy’s
    Deliahs Family of insane stupid brothers & Dad who’s nose has been bitten off also hunt the young pair of smitten teens.

    If this really is 400hp, the concern would be the weak 10 bolt rear.

      That is a issue if your wanting to race hard-core but as daily driver it hasn’t come into play. Also it is not a posi.rear end

    Rockford Files color! And the Rockford Firebirds were disguised Formulas with 350s or 400s.

      Mark, my first thought exactly! Ditch the chicken decal, repaint the same color, sideburns and a plaid sportcoat and you are Rockfish!

      I have one question. How well does this 400 hp engine perform on unleaded gas?

    Had the same car basically, was a 79 esprit, 301. 70k miles with a knock I bought for $700 from a used car dealer who was one if our customers. He took the car in on trade just because the body was so nice and it had low miles. Had our machine shop guy, Aldo Santini, in Highland, NY massage a 400 I bought from the body shop next door that had the pile of rust that used to be a Formula 400 it was in just for the engine. Auto trans though. Keith Black 10:1 pistons, healthy cam from Crane, had a Pontiac performance manifold and a Rochester that had sentimental value I kept rebuilding from car to car. Ran fine on 93 or 94 octane, valve guides were replaced and everything else that would give me a hard time with unleaded. A 3″ Dynomax mandrel bent exhaust off the manifolds to a stock location dual in dual out Dynomax muffler sounded great and moved exhaust just fine. Car was a monster, looked like a plain Jane Firebird with a little spoiler on the truck from the factory in Pewter Cloud. Someone came into the shop with a full set of Corvette rally rims, 8″ with center caps and rings for $50. The paint on the rims was a close enough match so you woukd think it was color matched. Wanted to break lose every time you took off so it got some wider tires on the wide rims, 255/50/15, helped some. On the highway I used to have fun with Mustangs that egged me on. A tractor trailer moved over into me while I was in the slow lane minding my own business. Loved that car. I’d imagine I’d make my money and then some off of it if I still had it today.
