How To Choose A Carburetor

Holley’s carburetor selection guide tackles the argument every muscle car owner has had at least once — what size carb actually belongs on this engine — with real CFM math instead of bigger-is-better folklore. The video breaks down why oversizing kills drivability, how vacuum and mechanical secondaries serve completely different kinds of builds, and where street and race carburetors part ways. It is aimed squarely at classic muscle cars and daily-driven builds. Watch the full guide before your next trip to the parts counter.

Chevy Small Blocks –Number-9

by Ross Mills

A hidden VIN code separates GM’s last true first-generation small block from any other 350, and most owners never learn where to look for it. The Vortec 5700 L31 quietly powered Escalades, Suburbans, and full-size trucks through the late 1990s, while its oversized cousin, the 400 cubic inch small block, carried its own quirks and a notorious overheating flaw. Read on to find out what separates these two small blocks from the rest of the Chevy family, and why one of them is still available brand new today.

The 1967 Chevrolet Nova SS looked like a mild refresh of Chevrolet’s compact Chevy II, but underneath was a genuine giant-killer: a 350-horsepower 327 V8 available for just $93 more than the base engine. Here’s how the Nova went from economy car to muscle car contender, and what the safety updates of 1967 changed for good.

History/Breakdown: 1963 Plymouth Sport Fury 426 Max Wedge

by Wes

No scoops, no stripes, just dog-dish wheels and a stripped interior, this 1963 Plymouth Sport Fury looks like nothing special until you learn what is under the hood: a 426 Max Wedge Super Stock V8 making an advertised 415 horsepower. One commenter says with modern tires and race gas, it would run 10-second quarter miles today. See why Mopar collectors call these early B-bodies brutes.

Legend holds that Carroll Shelby trademarked the ‘King of the Road’ name in a hurry after hearing Chevrolet wanted it for a Corvette — securing it for his new 428 Cobra Jet-powered Mustang instead. Shelby built the GT500KR for barely two months in 1968, producing just 1,053 fastbacks and 517 convertibles — 1,570 cars total. Independent road tests of the era clocked it at 5.4 seconds to 60 mph, numbers that placed it among the quickest American cars you could buy.

Chrysler Hemi from 2003—The Third Generation—part 5 of 5

by Ross Mills

Chrysler’s third-generation Hemi introduced a two-spark-plug-per-cylinder ignition system and eventually spawned everything from a fuel-saving 5.7-liter truck engine to a 590-horsepower 426-cubic-inch showstopper. Along the way, displacements ranged from 5.7 to 6.4 liters, with technologies like MDS cylinder deactivation and variable crankshaft timing added throughout its run. Read on to find out how one ignition change led to an entire engine family.

A Nassau Blue 1966 Corvette roadster carrying the L72 427, factory-rated at 425 horsepower and 460 lb-ft of torque, headlines Episode 213 of V8TV’s Muscle Car of the Week. The car comes from The Brothers Collection, and viewers split over whether visible exhaust smoke points to needed engine work or whether the car is still a near-perfect judged example. See which side of that debate holds up.

4 Cars That Feature Fords 4V COBRA ENGINE For UNDER $10K!!

by Wes

Ford built one of its best naturally aspirated V8s for the SVT Mustang Cobra and Ford GT, then quietly dropped variants of it into a Lincoln and a Mercury that almost nobody cross-shops for performance. The used market still hasn’t caught up to what’s actually under the hood of these cars. Read on to find out which two overlooked models carry genuine Cobra-engine credentials for a fraction of Mustang money, and what to check before buying one.

Buying a Collector Muscle Car

by Ross Mills

How a buyer phrases a single question to a seller can be the difference between an honest answer and a defensive “nothing’s wrong.” This entry breaks down the top mistakes collectors make when buying a muscle car, from rushed test drives to skipping legal history checks that are now fast and easy to verify. Read on to find out which habits separate confident buyers from ones who overpay.

Closer look at the exhaust system

by Ross Mills

A car’s exhaust system does more than make noise, though judging by the comments on this animated breakdown, the noise is what everyone remembers first. One viewer even swore they could hear a disco beat inside their own exhaust system by the video’s end. Underneath the soundtrack most drivers never think about is a chain of components managing pressure waves, sound cancellation, and heat that has to move fast enough not to cook the underside of the car. Watch to see what is really happening between header and tailpipe.
