This Coyote V8 build takes an unusual path to big power: first converted to carburetors, then switched back to fuel injection using an AEM Infinity standalone ECU and Ford Racing parts, ultimately reaching 625 horsepower and spinning to 8,500 rpm without any forced induction. Produced by Power Automedia’s EngineLabs team, the build has sparked a comment section full of swap ideas, from a 1970s Road Runner to a Fox-body Mustang. Watch the full build to see how a stock Coyote gets there.
Nick’s Garage puts a trusted double-pumper carburetor against a modern EFI system in a controlled, back-to-back dyno test, and the horsepower numbers surprised even longtime viewers. Just as much attention goes to an oil pump tip Nick shares mid-test, which commenters call one of the most useful things they have picked up from the channel. Watch to see which induction system actually wins.
David Freiburger uses this Roadkill Extra episode to preview the final chapter of the Crusher Camaro’s retro makeover while breaking down electric versus mechanical gauges — and the real tradeoffs most builders don’t consider until they’re already mid-install. It’s practical, hands-on advice from someone who has made both mistakes already. Watch for the gauge tips most builds skip entirely.
A 1979 Pontiac Trans Am arrives at V8 Speed and Resto Shop with rust hiding behind a poorly repaired firewall, and a factory stamping flaw underneath that. Rather than patch over both problems, the crew cuts the section out entirely and fabricates a replacement using a bead roller and a Pullmax, tools most home mechanics never touch. Fabricators in the comments call it some of the most impressive metalwork on the channel. The process reveals exactly what separates a real restoration from a quick fix.
Why does a Ferrari V8 scream while an American muscle car V8 burbles, even at the same displacement? The answer is buried inside the crankshaft, in a design choice most drivers never think about. Engineering Explained breaks down the flatplane versus crossplane debate that keeps resurfacing every time a new flagship car, from the Shelby GT350 to the Corvette Z06, makes headlines. It is a short explanation that changes how you listen to every V8 afterward.
This special report confidently explained why and when FCA was about to retire its legendary Hemi V8, and years of comments posted underneath it tell a very different story. Owners with hundreds of thousands of miles on their 5.7-liter Hemis, buyers racing to purchase one before it’s gone, and even an enthusiast writing in from Italy all showed up to correct the timeline. Watch the original case for the Hemi’s death, then see why the internet never let it stick.
HOT ROD put a $699 small-block turbo kit through real-world testing to answer the question every budget builder asks: does it actually work? The kit’s wastegate turned out to be the weak link — confirmed by a viewer who swapped in a real 50mm external wastegate and pushed a similar kit past 1,000 horsepower on a completely different engine. Watch to see what held up, what didn’t, and what it takes to fix it.
A creator known as MrOffAndOn set out to document a complete teardown and rebuild of a Dodge 5.9-liter 360 Magnum V8 — an engine with real Mopar small-block heritage that spent most of its life under truck hoods instead of muscle car fenders. Viewers have called it one of the most thorough rebuild videos they’ve found for this specific engine, with several thanking the creator directly for making it. Watch to see what a full rebuild actually involves, start to finish.
Nick and Vasilis chase 400 horsepower out of a freshly built Oldsmobile Rocket 350, comparing an Edelbrock intake against the factory cast iron piece on the dyno. Years later, viewers are still asking whether they actually hit the number — and debating whether a restrictive carburetor adapter plate held the engine back. Watch the full pull, then see what the comments say really happened.
Edelbrock breaks down one of the most consequential and most commonly misunderstood decisions in engine building: single plane versus dual plane intake manifolds. The difference in plenum design changes everything about how an engine responds at idle, off the line, and at the top of the rev range – and the comments make clear that most street builders should be leaning dual plane. Watch to see exactly why the wrong manifold can undercut a build no matter how good the rest of it is.
The 1969 Camaro looks simple from across a parking lot and turns genuinely complicated the moment real money enters the conversation — Hagerty’s Stefan Lombard has spent years mapping exactly why. From the ultra-rare ZL1 to the SS396 and Z/28, engine originality and structural condition can separate a $40,000 car from a $400,000 one. Read on to find out where first-gen Camaros actually rust, and what separates a real restoration from a convincing cover-up.
Engineering Explained gets inside Chevrolet’s Performance Build Center at the Corvette factory in Bowling Green, Kentucky, where the naturally aspirated LS7 and supercharged LT4 come together by hand. One engine chases power through raw displacement, the other through forced induction, and both end up in very different 2015 performance cars. See exactly what separates a 505-horsepower big-block philosophy from a 650-horsepower supercharged one.
A multi-part build series following a Chrysler 426 Hemi from bare block to running engine turned its comment section into a genuine history debate, with viewers tracing the Hemi’s roots back through the 1956 Chrysler 300B and, according to one claim, all the way to a WWII-era aircraft engine. Between the technical assembly detail and the borderline-religious reverence in the comments, this build says as much about Hemi mythology as the engine itself. Watch the full build.
A straightforward primer on Oldsmobile V8 engines has spent years quietly becoming a gathering place for Olds owners — 455 Rocket testimonials, a detailed home-built 400-horsepower Cutlass 350, and warnings about the engine family’s well-known low oil pressure. One commenter’s story about a Rocket 350, a forced sale, and a divorce he half-jokes he regrets more than losing the car sums up why this channel keeps pulling people back.
A mechanic demonstrates removing carbon buildup from piston crowns and the block deck using nothing more than WD-40 and a Scotch-Brite pad — and the comments turn into a genuine debate over the right way to do it. Viewers share a grease-dam trick for trapping debris, argue over scratch marks left by the scraper, and weigh in on when a rebuild needs a machine shop instead of a garage floor. The technique applies just as well to a muscle car big-block as it does here.
