How easy is it to rebuild a Chevy small block V8?

Chevrolet's famous small block V8 stands as one of the workhorse engines in American auto history, with its variants going into vehicles from hot rods to pickup trucks. But do you know that you can fully disassemble and completely restore one of these mills in just under four minutes? Well, as long as there's some assistance from time-lapse photography, that is. Hagerty created this short clip showing a dirt-covered small block turning from a frog into a prince. Thankfully, the time-lapse doesn't speed the process up too much, and it's still easy to see how all of the principal parts fit together. With all sorts of sensors and software helping to drive the modern automobile, viewing the internal combustion engine in its purely mechanical form is still fascinating. Related Video:

2023 Chevrolet Silverado HD reportedly getting mammoth torque

Chevrolet just gave the light-duty Silverado a significant round of updates. It hasn't detailed the changes it has in store for the heavy-duty model yet, but a recent report claims the truck will arrive with significant engine upgrades. Without citing sources, website TFL Truck reported that the current pickup's 6.6-liter Duramax turbodiesel V8 will return in the updated model. Its displacement won't increase, but its output will reportedly grow to 505 horsepower and a mammoth 1,085 pound-feet of torque. To put those figures into perspective, the 6.6-liter makes 445 horsepower and 910 pound-feet of twist in the 2022 Silverado HD; GMC's Sierra HD is available with it as well. Bumping the Duramax's output is a way to keep up with the competition. Arch nemesis Ford offers buyers who have extremely heavy things to tow 475 horsepower and 1,050 pound-feet of torque from a 6.7-liter turbodiesel V8. Over at Ram, the most powerful engine available in a heavy-duty truck posts numbers of 420 and 1,075, respectively. If the report is accurate, Chevrolet will enviably take the horsepower and the torque crowns in the segment. What remains to be seen is what effect the increases will have on the Silverado's towing capacity. As of writing, it's capable of towing up to 36,000 pounds (approximately 15 times the weight of a 2021 Mazda MX-5 Miata). Moving out of the engine bay, the 2023 Silverado HD will receive an updated exterior design that will again help differentiate it from the smaller, light-duty model. We're expecting the next round of updates will also bring new tech features, and it's reasonable to assume that the trim structure will evolve; Chevrolet might notably shift the HD in a more outdoorsy direction to satisfy a growing demand for off-road-focused trucks in the United States. None of this is official; Chevrolet is keeping its lips sealed about the updated Silverado HD. Full details will likely emerge in the coming months, and sales are tentatively scheduled to start in time for the 2023 model year.

Sunday Drive: Performance comes in many shapes and sizes

The Chevrolet Corvette has always stood out as a bastion of reasonably priced performance, and the latest 'Vette has that in spades. And while its expected starting price of around $120,000 certainly isn't cheap, it's an undeniable deal in the supercar world – remember, this thing'll do 210 miles per hour thanks to its 755-horsepower supercharged V8 engine. And did you get a load of that massive rear wing? Team Corvette's longtime foe, the Porsche 911, is similarly hellbent on ultimate performance. And as a reminder of how long the Corvette/911 rivalry has been melting tires we present the 1990 Porsche 911 as reimagined by Singer you see below. It's beautiful, it's green, and it's packing 500 air-cooled horsepower. You don't have to burn gasoline to go fast, as proven by the second-generation Tesla Roadster, which was revealed as a surprise late last week. Elon Musk says it'll be the quickest car in the world with a 0-60 time of just 1.9 seconds. And while you may not think of a semi truck when you think speed, the Tesla Semi can do 0-60 in 5 seconds flat unloaded, or in 20 seconds with a load of 80,000 pounds. Compared to today's crop of diesel semis, that's amazing. Continuing the truck theme, we present an artists rendering of what the next-generation Ram 1500 pickup may look like. Spoiler alert: Ram's mini-semi look is giving way to something much more modern. There may even be a first-of-its-kind split tailgate at the rear. And if you don't think the Ram 1500 has anything to do with performance, we should remind you that it's one of the cheapest ways to get a tire-shredding Hemi V8 engine in America. 2019 Chevy Corvette ZR1: All hail the 755-horsepower C7 king This is the first Porsche 911 to get Singer and Williams' 500-horsepower engine Tesla Roadster surprise reveal | 'Quickest car in the world' Tesla Semi Truck revealed: Here are the key details This could be the next-generation 2019 Ram 1500 2019 Ram 1500 spotted with split tailgate
