1967 Shelby GT500 427 Side Oiler Muscle Car Of The Week Video Episode #179

1967, Shelby gt500 with a 427 427 1967's, a redesign for the Ford Mustang. And of course, the Shelby cars went along for the ride, and it's interesting to note how the Shelby Mustangs evolved or how some would say devolved over time. The evolution of the Shelby Mustang is an fascinating path.

As many believe the cars started out at the peak with the 1965 GT 350, which was as much of a race car as ever unleashed on the public. It was light, nimble powerful, loud, uncomfortable and very pure. And so. Much so that the 66 GT 350 was made to be more of a driver friendly car.

And by 67 the cars, leaned even more towards the comfort and style side of the track. Now don't get me wrong, there's, still, awesome cars, but Ford realized that most people were never going to race their GT cars. So they refined them to increase the mass appeal, and you could go to your dealer and buy additional performance parts, or you could take the stuff out of your 67 car. But the turnkey version from the dealer was a much more. Refined car the 65 and 66 Shelby GT 350s were very popular cars and great performers. But for 67 Shelby turned it up well, a bunch of notches and added a big-block to the car and called it the gt500. The number 500 really didn't mean, much on a Shelby Mustang outside it being Shelby's chosen designator to distinguish the car from its small-block stablemate.

While the number 500 was appearing on cars that had NASCAR connections like the Galaxies, 500 the Shelby gt500. Never the NASCAR. The story goes.

That Shelby wanted a number higher than any other car. You could buy so 500 was decided because it was bigger than you know, say a 426 on a Semi car or 427 on a Corvette, regardless of the name, the gt500 commanded respect the day. It hit the streets when you stopped in at your local Shelby dealer in 67 to buy a gt500. It would have come with a 428 v8 under the hood.

But this one has a 427 side oiler under its hood. So the question is, how did it get there? Well, as you can imagine, many of these cars were. Purchased to be driven hard, and that meant many of the mild-mannered 428 s refused to the point of failure. And sometimes performance enthusiasts would return to their Shelby dealer and purchase the high-strung 427 as an upgraded replacement engine for the broken 428. And this was not a hard conversion to do because externally the 427, and the 428 are very similar and considering how detailed this installation is in our gt500.

We suspect that this was a dealer-installed 427 at some point, the 428. Debuted in 66 in the Thunderbird and Ford 7-liter galaxies, but it wasn't available in a Mustang until 1968 and technically the 428, and the Shelby was not a cobra jet as seen in the 68 cars, rather it was a police interceptor motor that was further hopped up by the Shelby team. They added their own cast aluminum intake, manifold dual, four-barrel, carburetors of performance, hydraulic camshaft and ended up with a very torque engine, producing 355 horsepower and 420 pound-feet of torque. And the 428 was. A great Street engine that offered a nice mix of power and torque combined with mild street manners to make for an enjoyable and reliable car.

427, 428, what's, the big deal right? Well for a proper correct car. It needs to have the engine that it was born with in all Shelby. Gt500. S, were born with 428, except for one, which is a very well known car. Nicknamed the Super Snake.

You see the 427 is a radically different engine from the 428, the 427 features, a stronger block with cross bolt of main caps higher. Compression tighter tolerances and a high revving personality. Thanks to a solid mechanical valve train and a revised oiling system that fed the main bearings from additional oil galleries on the side of the block. And thus, the nickname the side oiler, the 427 was Ford's racing big-block engine with lineage going back to the early 60s and was never factory installed in any Mustang, except for the Super Snake. The result is a gt500 with a much different attitude than the regular 428 cars. The 427 has a. Nasty idle that makes more power up top and potentially moves this car out of the realm of daily driver reliability and into weekend warrior status, which is not to say you couldn't drive this car every day as the gt500 retained, the high performance suspension and driveling of the earlier cars, but additional creature comforts were added, including power steering power brakes and some cars even came with air conditioning.

And if they wanted to use style as a tool to sell cars, they've certainly hit. The nail on the head with the 67 Shelby cars, numerous body modifications transform the 67 Mustang into the car. We see here, including fiberglass nose pieces, a longer hood with the scoop, the inboard high beam headlights, low quarter, mounted rear brake ducts upper quarter window cockpit air vents, the ducktail, rear spoiler. And of course, the Cougar sequencing taillights the base wheel was a steel unit with Thunderbird hubcaps. But many chose to upgrade to the Shelby cast aluminum wheels, Goodyear tires.

Are always proper on a Shelby car because of his relationship with the tire manufacturer. And this car is wearing its original Acapulco blue, exterior color set off by the white gt500 stripes and the black interior the cockpit features. The integral roll cage complete with the retracting inertia, reel, shoulder belts, which is apparently some of the first of their kind installed on an American car. And interestingly, Shelby cars moved the rally pack gauges from the steering column and put them down.

Below the radio, which actually made them a little harder to see, but they did upgrade the gauge pod with store Warner Green line gauges. So although it's true that this car might not be as authentic considering it. No longer has the original 428. We think the 427 side oiler is an engine choice that team Shelby would approve of after all even Carroll Shelby himself had a heart transplant. Some might argue that the 428 was a better engine for street driving.

But then again, this 427 car is gone. Well over.78,000 miles. So somebody drove it a lot I don't know, what do you think would you want the more mellow 428 or the high-strung 427 in your Shelby I think I'd take the 427 share your thoughts with us on our Facebook page, YouTube comments or on our website at muscle car of the week, and we'll see you next time with another cool car from the brothers' collection.
