7 V8s With A Reputation For Being Nearly Indestructible – Jalopnik

Who would not just like the uncooked energy provided by a V8, in case you can afford the gasoline, that’s? But it isn’t simply the horsepower that attracts so many people to those engines. Some V8s are among the many longest-lasting engines on the street as we speak. There are a number of examples of drivers taking their V8-equipped autos, particularly pickups, over 1,000,000 miles. That’s fairly the feat.

Some examples of those million-mile accomplishments embody a 1UZ-FE 4.0-equipped Lexus LS 400 that already had practically 900,000 miles on the odometer when it was purchased by a Road & Track author for the categorical goal of taking on 1,000,000. There are a few examples of homeowners driving one other Toyota V8 engine, the 2UZ-FE 4.7, previous the million-mile mark. Other examples embody Frank Oresnik who drove his 1991 Chevy Silverado, which featured a small-block Chevy 350, over 1,000,000 miles. David Mueller did the identical factor together with his 2002 F-350 Super Duty.

An engine would not need to go 1,000,000 miles to reveal its sturdiness, although. The Ford 4.6-liter Modular 2-valve took all types of use and abuse as the usual engine utilized in Crown Victoria Police Interceptors through the Nineties and 2000s, and will nonetheless go for a whole lot of hundreds of miles. Then there’s GM’s Vortec 8100, an engine so rugged that it was not solely put in Chevy and GMC vans, but in addition in boats and RVs. There was additionally the versatile Chrysler LA 318, which earned the repute of being “bulletproof.”

Lexus debuted its first mannequin in 1989, and little doubt wished its comparatively new luxurious model to be related to sophistication and luxury, however that may require worthy engines with high-end efficiency. Enter the 1UZ-FE 4.0, an aluminum block, oversquare 4.0-liter V8, with 4 camshafts and 32 valves. The 1UZ displaced 3,969 cc, with an 87.5 x 82.5 mm bore and stroke. It made round 250 horsepower and 260 lb-ft of torque, not precisely earth-shattering in our trendy turbocharged period, however not too shabby for 1989. In reality, this engine is usually described as “overengineered”.

The automobile it might be matched with, the Lexus LS 400, had its personal share of overengineering. Born from a billion-dollar secret undertaking at Toyota, it spent six years in improvement and went by way of eight proposals for its ultimate design. There have been 50 clay fashions, about 450 automobile prototypes, and 1.67 million miles of testing.

All of that testing and engineering paid off. One one that might bear witness to the close to indestructibility of this engine is Matt Farah from Road & Track. He was offered with the chance to purchase a 1996 Lexus LS 400 with 897,000 miles on it. Farah acquired it with the objective of taking it over 1,000,000 miles. After 4 years of driving it himself, in addition to lending it out to buddies, acquaintances, and other people he did not even know, he reached the objective of placing seven digits on the unique engine.

Toyota adopted up the 1UZ with the 2UZ-FE 4.7, however this engine wasn’t to be put right into a luxurious sedan. Built with a rugged cast-iron block, it was meant to final by way of put on and abuse because it powered massive SUVs and pickup vans. A 2003 Land Cruiser Amazon outfitted with this engine might crank out 235 hp and 320 lb-ft of torque with a 9:6:1 compression ratio. It wasn’t breaking any data within the energy division, however it was engine, nonetheless. The 2UZ-FE 4.7 would go on to be featured within the Tundra, Sequoia, LX 470, and GX 470.

Several years in the past, Louisiana man Aaron Morvant drove his 2UZ-FE-equipped 2007 Toyota Tundra previous the million-mile mark. In reality, he had purchased the truck to make use of as a contract sizzling shot driver, particularly due to Toyota’s repute for reliability. (Toyotas make up the vast majority of our listing of autos you’ll be able to count on to drive for 300,000 miles.) The truck as nonetheless operating nice after 1,000,000 miles, despite being banged up. 

Earlier that very same 12 months, one other Louisiana driver, Vic Sheppard, drove his Tundra previous the million-mile mark. His truck was in significantly better form, and nonetheless had the identical transmission and paint job. Toyota traded him a brand-new Tundra for his previous truck in order that its engineers might examine it. When they hooked the engine as much as a dyno, they found it ran higher than a few of Toyota’s new engines. Making the story much more fascinating, Vic and Aaron are buddies.

If you lived within the U.S. through the Nineties and 2000s, it might have appeared to you that each police automobile within the nation was a Ford Crown Vic. It actually appeared that method to us. Well, we weren’t imagining issues. At one level, as much as 85% of police vehicles within the nation have been Crown Victoria Police Interceptors. If there is a sort of automobile that can put an engine by way of in depth use and abuse, it’s a police automobile. Further testifying to this engine’s sturdiness, there have been loads of taxi cabs on the time that have been Crown Vics as nicely. Taxi cabs, with their quick journeys, frequent idling, and begins and stops, aren’t sort to engines both. 

This was one other hearty engine with a forged iron block, on its authentic model not less than, together with a nodular iron crankshaft and metal camshafts. Ford says that “the Modular engine design focuses on low friction, best-in-class sealing, long-term durability, and increased bottom-end stiffness.”

The 4.6 would additionally present up within the Mercury Grand Marquis, Lincoln Town Car, and sure Mustangs. It was even put into the F-150, beginning in 1996. One Hagerty author who frequents junk yards famous that he usually finds former Police Interceptors with 100,000 to 200,000 on the odometer and even discovered a former Crown Vic taxi cab with 400,000 miles on it.

In the early 2000s, GM apparently checked out massive block V8s and determined they only weren’t sufficiently big. This might need had one thing to do with the occasions and the truth that different truck makers like Ford and Dodge have been creating V10s, however regardless of the motivation, GM’s mission was to create a majorly overbuilt V8. The Vortec 8100, also called the RPO L18, was 496 cubic inches of uncooked energy. It had a 4.25-inch bore x 4.37-inch stroke. It had a forged iron block, 4-bolt major caps, and 18-bolt forged iron cylinder heads, every of which weighed 78 kilos. It might produce 340 hp and 455 lb-ft of torque.

This beast was made for full-size vans, SUVs, motorhomes, and boats. Its 761-pound bulk was not meant for a coupe or another passenger automobile, for that matter. So it went into Silverado and Sierra 2500/3500s, heavy Suburbans, and vans, together with the aforementioned RVs and boats. That hasn’t stopped folks from retrofitting them into their Camaros, Corvettes, and Novas. Of course, in doing so, they’ve needed to swap out the unique forged iron elements with lighter ones. That consists of changing these large heads with CNC aluminum heads.

The sturdiness of this engine has loads to do with the trials it went by way of in improvement and manufacturing. Because it was meant for use in boats, GM examined it by operating it for 55 minutes at full throttle, then 5 minutes at idle, 300 occasions.

Reliability would not at all times come from striving for glory or attempting to be probably the most highly effective, or fascinating, for that matter. Sometimes it is only a matter of being constructed to do the job. That was the case with the Chrysler LA 318, launched in 1967. When it got here to V8 engines, the 318 was the little engine that might. It was a modest 318-cubic-inch small block with an much more modestly-sized 3.91-inch bore and three.31-inch stroke. The first engines cranked out a decent 230 horses, which ultimately fell to 145-155 hp through the Nineteen Seventies — undoubtedly not striving to be probably the most highly effective, however that is all proper. 

What stood out in regards to the LA 318 was its sturdiness. Its uncomplicated design gave it the repute for being bulletproof. So it turned up in every little thing from commuter autos to mild vans, and even cop vehicles. Models that held this engine included the Dodge D100 pickup, Plymouth Duster, and Dodge Dart.

A author at Hot Rod tells their story of taking a 318 out of a Diplomat police automobile that had 120,000 miles on it, and placing it into an A-body with out machining it in any respect — they only changed the rings and bearings. The engine ran for one more 100,000 miles when the author opted to exchange it with a much bigger engine. Upon inspection, it was in such fine condition that they determined it did not want a rebuild.

Did you understand that from 1929-1955, Chevy solely produced 6-cylinder engines? That all modified in 1955, when the automaker launched its small block V8. It was a 90-degree V8 with overhead valves and a pushrod valvetrain — a design that may affect generations of Chevy small blocks to come back. The Gen I small block, although, wasn’t probably the most highly effective engine ever constructed. It might crank out 198 horsepower, that’s in case you opted for the four-barrel carburetor. That energy output would regularly enhance, particularly with the addition of gas injection simply two years later, upping the horsepower to 283.

The first small-block V8 from Chevy can be put in within the 1955 Corvette. As it advanced, varied variations of the small block would discover their means into the Camaro, the Firebird, and numerous different GM merchandise. It would additionally develop into an engine choice for Chevy pickups. One instance can be the 5.7L V8, also called the “Chevy 350.”

In 1996, Wisconsin man Frank Oresnik purchased a 1991 Silverado with a Chevy 350 in it, and 41,000 miles on the odometer. He would go on to place about 85,000 miles on it per 12 months delivering seafood. By 2008, he had pushed it previous the million-mile mark. At that time, he put the truck up on the market on eBay with a minimal bid set at $30,000, and was later shocked nobody bid on it. Come on, Frank, it is a Silverado with 1,000,000 miles on it. Maybe he was among the many “I know what I got” crowd.

If you are not updated on in-depth Ford historical past, you is likely to be shocked to search out out that one of many best-known Ford truck engines is not technically a Ford engine. Ford collaborated with International Harvester within the Nineties to give you a V8 diesel to exchange the 7.3L IDI, which had additionally been constructed by International. The results of the collaboration was the 7.3L Power Stroke, first provided in 1994 for the F-250, F-350, and F-Super Duty. Early variations of the 7.3 had simply 210 hp, however later fashions provided as a lot as 275 hp and 525 lb-ft of torque. By 1999, Ford had offered a million vans that housed the massive diesel, and that quantity would double by 2002.

The 7.3L Power Stroke featured a forged iron block, in addition to cast metal connecting rods and aluminum pistons in earlier engines. Ford ultimately discontinued the engine in 2003 to adjust to emissions requirements, however you’ll find loads of them nonetheless on the street as we speak. 

Some credit score the engine’s sturdiness to its easy design and the truth that it wasn’t fairly highly effective sufficient to be harmful. And with that legendary sturdiness, we now have one other million-mile engine story. David Mueller purchased his 2002 F-350 Super Duty new and began utilizing it to ship heavy RVs, a few of which weighed over 11,000 kilos. He averaged 600 to 800 miles per day, and by 2011, he had put 1,020,000 miles on the truck.
