Hot Rodding Made Simple: Affordable Turn-Key Crate Engines

With the availability of crate engines increasing, even aftermarket companies such as BluePrint Engines are offering up potent LS-mill crate engines to satisfy even the most die hard enthusiast.

If there were ever a time to jump into the hot rodding game, now would certainly qualify. View any number of classified ads and you’re guaranteed to either find a running project car or a full-roller (sans drivetrain), on the cheap.

Most of them will easily fit the budget, any number of crate engines and provide you with a formidable driver. Now more than ever, aftermarket companies are churning out a multitude of parts, components, and even full-tilt race engines. Of course, our garden variety readers don’t necessarily need to delve into the world of high-zoot race mills, however, many still love to go fast on a cheeseburger allowance.

A clean assembly room prohibits dust or air-borne contaminants from entering the bare engine, which could damage the engine.

As matter of fact, most of the aftermarket drivetrain industry is offering up crate-style electronic overdrive transmissions with controllers, and even boxed up rearends ready to bolt-up to the frame. Trust us, the aftermarket is running full steam ahead and there really is no end in sight. Though, finding a project car is only half the battle.

Luckily, finding a reliable engine for your project car or daily driver is even easier. To clear the air, we’ve located and described each of our favorite small-block Chevy crate engines available through the aftermarket. We hit up some of the most popular engines available and include all you’ll need to know about each engine and provided dyno numbers where applicable. We assure you, you’ll find what you’re looking for and well within  your price cap. Read on to find out which small-block Chevy crate engine is right for you. It really couldn’t be any easier…

A Sign Of The Times

In years past, supplying your ride with a decent powerplant turned out to be a daunting task. Luckily for most, these days it’s not terribly difficult as most aftermarket companies are banging crate engines like the Mission Tortilla factory. Just take a look around at your next local cruise or drive-in dive, don’t be surprised to find a pre-assembled crate engine sitting between those framerails.

Sure, a custom built mill offers up supreme potential and bragging rights, too. However, with the availability of off-the-shelf, fully built engines, that option is losing momentum. Not to mention that most aftermarket companies, which provide crate engines, offer up warranties to boot!

Drop In And Go

As you can see, there really aren’t any drawbacks; just drop and go. Although handling your very own engine conjures up a sense of self-importance, there’s really no beating a combination that has already been developed and tested like a turn-key crate engine.

The crate engine concept is not a new idea either. For years, powerhouses like GM Performance Parts and Edelbrock have been producing the ultimate bang for your buck in affordable crate engines.

The cross-hatch markings inside each cylinder illustrate the honing process. This particular short-block is ready for the top end assembly to be installed.

It was only until recently, privateer performance shops like Pace Performance, Blueprint Engines, and Patriot Performance have been able to also supply the aftermarket with fully assembled, traditional crate engines to fit any variety of wallets.

Crate engines offer up the racer lifestyle at only a fraction of the cost.

The Crate Engine Phenomenon

More or less, consumers can simply flip the pages of any number of catalogs available or just surf the Internet to locate a desired powerplant. It’s painfully simple. However, there are a slew of terms that are frequently used but offer up little if any explanation to what they truly mean.

The align-honing process is quite complicated. While we can’t go in depth with the procedure, align-honing the block before assembly is a critical step during the engine build. Check with your favorite crate engine supplier and ask for more details regarding how your crate engine was machined and assembled.

Generally speaking, defining a crate engine is simple and for our purposes, “crate engine” refers to an engine that’s shipped complete, at least up to the cylinder heads. For demonstration purposes, the engines you see here include small-block Chevy turnkey engines, which come complete from carburetor to the oil pan.

These days, it’s normal to see most crate engine blocks in the four-bolt main architecture. The four-bolt main blocks are stronger and more reliable.

With four bolts securing the main bearing caps, the amount of flex within the crankshaft as compared to the weaker, two-bolt main structures are reduced. However, that’s not to say a two-bolt main variation couldn’t handle daily driving with moderate horsepower figures.

While some higher-end crate engines rely on a set of aftermarket fasteners, some crate engines are still built with the factory-style bolts. Ask your local crate engine supplier which types of fasteners were used in your engine before you purchase it.

Crankshafts also play a vital role in crate engines. Again, it all comes down to how you plan on using your new-found power. For the most part, a cast crankshaft can handle most, if not all of your driving duties (Up to 600HP). Cast crankshafts are still plenty strong, although if you plan on a more demanding environment, than finding a crate engine with a cast crankshaft could outweigh its increased cost. If you plan on adding more RPM, boost or nitrous, a forged unit can certainly qualify to meet those needs.

Again, just as important as the crank are the pistons, too. Pistons can also come in three different flavors: Cast, hypereutectic and forged pistons. Depending on the supplier, again, a cast piston would be able to handle a variety of driving styles.

The difference in these two types of crankshafts, visually, is hard to discern. However, the forged (far left) crankshaft can withstand more rpm and punishment than its weaker, albeit, more affordable cast crankshaft.

Moreover, if your driving style includes some bolt-on upgrades down the road such as, nitrous or a supercharger, the forged internals can save you a ton of headaches in the long run.

Cylinder Heads

Crate engine suppliers like BluePrint Engines are now including their own custom set of aluminum cylinder heads to a variety of their crate engines. These aluminum 195cc lungs from BluePrint include performance ports and combustion that are as-cast, high-quality 21-4n stainless steel valves, Viton seals, double springs, and other high-performance features.

Cylinder head options, too, are populating a majority of turn-key crate engines. As it’s become cheaper to produce race-style cylinder heads, they’re becoming quite the norm on many crate engines.

Depending on your application, an iron set of lungs is the most affordable option on a crate engine rather than the aluminum route. The trade off occurs as iron is more detonation prone and retains heat longer. That’s not all bad news either  but the aluminum option means a lighter front end and is easier to port and repair when needed. Some cylinder heads packages (depending on the supplier) come with complete CNC machining for superior flow.

Again, it’s important to make sure you cylinder head selection is properly matched to your specific rodding needs. Call ahead to your crate engine supplier and ask for more information.

Today's modern crate engine packages contain top-notch engine building techniques, block quality assurance testing, and high-quality components, which add strength and promote longevity.

Though a long-block crate engine comes nearly complete aside form the intake manifold, the engines which are sporting a manifold can come in two options including either, dual or single-plane manifold designs. For daily driving, a dual-plane manifold can provide a flat torque curve; keeping the power right where you need it.

However, depending on the cubic-inch and camshaft size, a single-plane manifold might offer up the best of both worlds. Of course, nearly all of these circumstances come down to your specific needs and personal budget. It’s important to keep these key elements in mind when you’re searching and preparing to purchase your turn-key crate engine.

If you plan on a simple alternative to what you’re currently wheeling, a complete, iron-headed small-block can satisfy nearly any hot rod. However, if you plan on some weekend warrior-like racing, be prepared to spend a little more on upgraded internal components like a forged crank and pistons.

Patriot Performance 383 Stroker
Horsepower: 501
Torque: 492
Cost: $5,385

Knowing that the foundation for every serious build begins with the block, Patriot began their crate-engine 383ci program utilizing only the best from the aftermarket. Patriot Performance begins with Dart’s versatile line of SHP short-blocks. Internally, the Dart blocks are adorned with an Eagle rotating assembly, including KB forged slugs with a flat top. Additional internals consist of their large, hydraulic camshaft spun by a double-roller timing set.

Patriot Performance begins thier 383 Stroker package with a Dart’s line of SHP offerings, which are packed with an Eagle rotating assembly and KB pistons.

For heavy breathing, Patriot relies on its very own set of aluminum Patriot cylinder heads. These high-flow heads come with 2.02-/1.60-inch intake/exhaust valves, 64cc chambers, and 190cc intake runner volumes. A set of Scorpion or Harland Sharp roller rockers are relied on for valve control.

Patriot then installs a dual plane Dart manifold and even adds an MSD HEI Streetfire ignition to the mix as well. Of course, it’s all dyno tested to the tune of 501hp! Do the math, that’s $10.74 per horsepower; an unbelievable package for the everyday cruiser or weekend warrior drag car.

Patriot’s philosophy is spawned from their service to producing reliable packages.
