Dart 427

1208chp 04 O  12 Crate Engines Dart 427 2/13

Big-inch small-blocks used to be exotic high-dollar propositions. They’re still exotic, but Dart has made it much more affordable to plop one in your muscle car. The company has been designing its blocks to play nice with big-bore, long-stroke rotating assemblies for quite some time, and it’s now using that know-how to build its own short-blocks. The foundation of the Dart 427 Chevy is an SHP block bored to 4.125 inches. It’s fitted with a forged rotating assembly with the option of either flat-top or -20cc pistons. All you have to do is throw on some heads and an intake, and this thing’s ready to rip. With a set of Dart Pro 1 heads and a mild hydraulic roller cam, Dart says the 427 will dish out 550 hp on the dyno.

Summit/Chevrolet Performance LS 327

Who says you need to go broke to jump on the LS bandwagon? Available through Summit Racing, this Chevrolet Performance LS 327 long-block offers big bark out of a small package. It’s essentially the same durable 5.3L motor that powers millions of fullsize GM trucks and SUVs. Based on a rugged six-bolt iron block, the LS 327 is fitted with a nodular iron crank, powdered metal rods, and 9.5:1 hypereutectic pistons. Capping it off are cathedral-port aluminum heads capable of flowing well over 300 cfm when fully ported. Since it’s sold as a long-block, sourcing an intake manifold and water pump is up to the end user. If it sounds like a perfect recipe for some mild boost, you’d be correct in your assessment. Boosting one of these long-blocks to 8 psi is good for well over 500 hp, and the stock-block can handle 1,000 hp without a hiccup.

Big-block Chevys have always been associated with big power and big money. Fortunately, thanks to Speedway Motors and BluePrint engines, you can now step up to big-block power without going broke. Available exclusively through Speedway Motors, this 496 produces 590 hp for just $6,999. The combo starts life as a GM Mark IV block, and after boring it 0.060-inch over, BluePrint stuffs it with a forged crank and rods, and 10.1:1 hypereutectic pistons. Aluminum rectangular-port heads and a dual-plane intake provide the airflow, and a 242/248-at-0.050 hydraulic roller cam actuates the valves. The 496 comes complete with the exception of a water pump and carb. Finally, there’s now an affordable way to lay some big-block–style patch.

Competition Products 383

While it’s certainly possible to build much larger small-blocks these days, the good ol’ 383 keeps chugging along. The same balance of performance and value that made it popular decades ago still applies today, and Competition Products’ 383 proves the point. For a little over $4,000, it kicks out 410 hp and 450 lb-ft. The company starts with a four-bolt block, punches it 0.030-inch over, then fits it with a cast Scat crank, steel rods, and 9.5:1 hypereutectic pistons. The short-block breathes through aluminum cylinder heads, a dual-plane intake, and a dyno-tuned carb, all from Edelbrock. All you have to add is a water pump, and this puppy’s ready to fire up.
