1993 Chevy Cummins K3500 on 2040-cars
Adkins, Texas, United States
This Chevy is a 1993 model with a 1997 Cummins. (215 pump) It has a 47RH, and 241DHD. I built every part of this conversion. It is not a kit conversion. Since I put the engine in, I've put 30,000 trouble-free miles on it. Now I have broken stuff along the way, but it was my fault, not the truck's.
It started as an almost stock engine. Just free mods and timing. I ran it like that until I broke the stock input shaft getting onto the interstate. I put in an ATS input shaft and ATS billet flywheel, and did another full tranny rebuild. Eventually I put twins on it. Started with he351cw over bht3b. I ended up replacing the 3b with a 4c, and went from an "over/under" setup, to a "side by side" setup. The truck is a pulling monster. Has over 500 horsepower, and over 1000lbs of torque. It gets up to 24mpg on the interstate via the 3.42 gears. At 75mph, it does 1850rpm. The lowest mileage I've gotten since the conversion was all in town, and that was 19mpg. But this truck isn't about the mileage. It's about the adrenaline rush you get whenever you punch the throttle. The twins spool loudly and quickly. They are lit by 1500 rpm, and past 50psi by 2000rpm thanks to the 9cm exhaust housing on the 351cw. The truck is and isn't 4wd. Right now, I've taken out the front drive line. It's got 3.42's in the rear, and 4.10's in the front. My plan was to put a Commonrail front end under it, and put 3.42's in the front as well. But I've grown tired of this hobby, and it's someone else's turn. At this point, it is a good daily driver with very good street manners. You could dial out some fuel and work this truck too if you wanted. It starts faster than any Cummins I've ever seen, and it does it without needing throttle input. When it's warm, you can't even try to bump it over without it starting. I've used Hobbs switches to control overdrive and lockup. I located them under the 4wd trim. You can adjust the shift points while you are going down the road. If you want, you can adjust them to even lock up in third and do a locked shift to overdrive, and it will all still work like a normal automatic. I've also put in a three-position mystery switch. You can run it in "auto" and just leave the truck alone. But you also have the options to force or defeat lockup. This is useful for pulling heavy in the mountains. Once the EGT's start to get hot, you can unlock the converter and they will cool down. You can run it like that until the tranny starts to get warm. At that point, you can force lockup and the tranny will rapidly cool back to 125*. The cooler I put in is massive. The switch also comes in handy on the dyno, as you can force lockup and floor it without it kicking out of lockup. At that point, it is running like a manual tranny, and if you are driving and try to come to a stop, it will not downshift unless you change the switch to defeat lockup, or auto. It will stay locked up so tight, it will kill the engine. The truck is still a project truck. You could tidy it up and call it done, or you can keep working on it. It's wicked fast, and will run the 1/4 mile in high 13's launching in 2wd. It sounds good, and has always been reliable for me. But it's time for it to be someone else's project. This truck is not street legal in Texas. It needs the reverse lights hooked up and mudflaps put on to pass inspection. So if you are planning on buying it, you can drive it at your own risk, or trailer it. The reverse lights just need a connector for the tranny, then run the hot to the lights. Here is a list of what I've done to it that I can remember: HEAD: Head gasket Head studs (ARP 625) Clearanced rocker pedestals New valve guide seals Hamilton billet pushrods with 10* titanium valve keepers Hamilton 165lb beehive valve springs AIR: Three piece pulse manifold HE351cw over HT4C (2400cfm/149lbs per minute) 94-98 intercooler FUEL: Contagious 7x12 injectors 215hp injection pump 181 delivery valves Benched AFC with modded foot for rack travel HAMILTON: Billet pushrods with 10* titanium valve keepers 165lb beehive valve springs PEAK: 4k governor spring kit TRANNY: 47rh controlled with Hobbs switches MagHytec double deep pan Mystery switch to force lockup, defeat lockup, or run in auto ATS billet flywheel ATS billet input shaft DTT master rebuild kit DTT 4.4:1 apply lever DTT billet band strut DTT zero leak servos DTT upgraded OD piston with O-ring DTT extra clutches per pack DTT valve body DTT billet triple disk torque converter New over running clutches New governor Cooler is 1998 Dodge Ram A/C condensor with another cooler stacked on top of it.

GM recalling 686k Lambda-platform models for hatch repair
Fri, Jul 10 2015General Motors is recalling 686,287 units of its Lambda platform crossovers. On models equipped with a power rear hatch the system can potentially fail. This campaign includes the 2008-2012 Buick Enclave, 2009-2012 Chevrolet Traverse, 2007-2012 GMC Acadia, and 2007-2010 Saturn Outlook. According to GM's documents to the National Highway Traffic Safety Administration (as a PDF), dirt can get into a portion of the strut that holds up the hatch and cause the part to prematurely fail. There's a redundancy in place called the Prop Rod Recovery system that's designed to shut the liftgate if there's a malfunction. However, if the breakdown happens too quickly after the hatch is opened the prop rod might not work the way it's supposed to. If someone were in the way of the falling liftgate, they could be hurt. For the repair, dealers will update the software for the power liftgate actuator motor control unit to prevent the hatch from closing so quickly. They'll also check the operation of the system afterward.

The affected vehicles, equipped with the power liftgate option, have gas struts that hold the power liftgate up when open. These struts may prematurely wear and the open liftgate may suddenly fall. CONSEQUENCE: If the open liftgate unexpectedly falls, it may strike a person, increasing their risk of injury. REMEDY: GM will notify owners, and dealers will update the software for the power liftgate actuator motor control unit so that the motor will prevent the rapid closing of the lift gate, free of charge. The manufacturer has not yet provided a notification schedule.
The U-2 spy plane needs high-performance cars to help land
Thu, Oct 15 2015Typically, aircraft deploy their landing gear from three main points. Most military aircraft, for example, deploy two gears at the back and one forward, like a tricycle. Some civilian aircraft flip the layout, with two in front and one in back - tail-draggers. The U-2 Dragon Lady is wildly different than any of these. With a 103-foot wingspan but a body that's just 63-feet long, the layout of the U-2 makes a traditional landing setup infeasible. Instead, the U-2 utilizes a pair of wheels, one up front and one in back. With such a bizarre layout, landings are so tough that since the U-2's earliest flights at Area 51, the US Air Force has used high-performance chase cars to guide the pilot down safely. The landing process isn't over there, though. As this video from Sploid shows, balancing out the aircraft to fit the detachable "pogos" – think training wheels for spy planes – is a comical procedure requiring a number of airman using their full body weight to even out the U-2. This video also recaps some of the great vehicles that have served as chase vehicles for this legendary spy plane. They include Chevrolet El Caminos, and the Fox-body Ford Mustangs so favored by the California Highway Patrol. For the last several years, the USAF has utilized products from General Motors, using fourth-generation Chevy Camaros, before switching over to the Pontiac GTO and most recently, the awesome Pontiac G8. It's fair to say that if you're a gearhead in the Air Force, this is the job you want. Check out the video, embedded up top.

Junkyard Gem: 1986 Chevrolet Sprint Plus
Fri, Jun 16 2023General Motors sold second- and third-generation Suzuki Cultuses with Geo or Chevrolet Metro badging in the United States from 1989 through 2001 model years, and we've all seen plenty of those cars on the street over the years. The first-generation Cultus was sold here as well, with Chevrolet Sprint badges, and I've found a rare example of the Sprint five-door hatchback in a Northern California car graveyard. The Chevy Sprint first appeared on the West Coast as a 1985 model, then became available everywhere in the United States for the 1986 through 1988 model years (in Canada, it was sold as the Pontiac Firefly). It was available here as a hatchback with three or five doors; for 1986 only, the five-door was badged as the Sprint Plus. Soon enough, The General would be selling many more Asian-built cars with Detroit badges here. Isuzu I-Marks were sold as Chevrolet/Geo Spectrums starting in the 1986 model year, while Daewoo provided the Pontiac LeMans two years later. Under the hood, a 1.0-liter three-cylinder rated at 48 horsepower. The five-door Sprint cost $5,580 in 1986, which was $200 more than the three-door (those prices would be $15,445 and $14,891 in 2023 dollars). I've documented seven discarded Sprints prior to this one (including an extremely rare Turbo Sprint), and all of them were three-doors; we can assume that price was the most important factor for Sprint buyers. Gasoline prices were crashing hard during the middle 1980s, but memories of gas lines and odd-even-day fuel rationing from 1979 remained strong. What cars competed with the '86 Sprint on sticker price? Well, there was no way to undercut the hilariously affordable (and terrible) Yugo GV, which cost $3,990. The much bigger (but still pretty bad) Hyundai Excel listed at $4,995, while Toyota would sell you a sturdy (but zero-fun) Tercel starting at $5,448. Even the wretched Chevy Chevette — yes, it was still available in 1986 — cost $5,645. The original buyer of this car was willing to shell out an extra $395 to get an automatic instead of the base five-speed manual. That's about $1,093 in today's money. This car must have been slow. By the end, the doors were held shut with duct tape, but it still stayed alive until age 37. 53 miles per gallon on the highway! It does everything. The camels of the highway.
