Preassembled ready to run performance crate engines have become the predominant source of power for classic truckers and rodders over the course of the last decade or so-and for good reason. The average Joe with little in the way of machining or engine building prowess (like me) has realized that picking up the phone or logging onto a website and ordering a professionally built partial or complete engine from a reliable source is by far faster, easier, and in some cases less expensive than building one from scratch-either on our own or through a network of subcontracted machine shops and builders.
In the not too distant past (it's amazing how fast a couple of decades can whiz by) the only things available through the local OE dealership chains were new or remanufactured replacement engines. Those replacement engines were just that, low power, pollution-controlled surrogates engineered to power the standard grocery getter of the day. Sure, most areas of the country did have a few local backyard performance wizards who built racing engines for the hard-core local gearheads, but they often did this as sidelines to their day jobs-leading potential customers to long delays for these services, if they could get on a waiting list at all.
As the automotive high-performance hobby grew so did the market for high-output powerplants. And this in turn motivated some of those talented backyard builders to graduate from building engines for their local circle of friends and acquaintances to opening small businesses and providing performance tuning and rebuilding services to the general public. As the rodding hobby grew and became a large and accepted segment of the public at large the best of these backyard builders took the plunge and turned their hobbies into full-time endeavors. And it wasn't long before these new small business owners saw an opportunity and began building and selling turnkey engines along with their tuning and rebuilding services. It didn't take that long before the Big Three noticed the growing hot rod hobby and turned their attention, and that of their engineering departments, from a narrow focus on organized racing and their own limited offering of factory performance cars to the burgeoning performance aftermarket. As time passed the OE realized the advantage and potential of offering competitively priced performance crate engine packages, and they've all developed relatively large selections for enthusiasts to choose from these days.
As I touched on earlier, it's a heck of a lot easier to peruse the wares of both the crate engine aftermarket and the OE automakers than it is to research, price, and collect the myriad of components needed and then to attempt to assemble a performance engine on our own. Well, I guess that's not entirely true, there is some research involved in shopping for a crate engine. But nothing like what it takes to educate ourselves on what cam grind will offer the performance we want in our desired rpm range, or what compression ratio is going to work with the crappy pump gas we've got to live with these days.
Today's crate engines (either those from the big automakers or the performance engine aftermarket) are built using fully tested components and combinations. And nearly every one of these companies is careful to test and evaluate what they build and sell. And today's professional high-performance engine manufacturers and builders are extremely good at validating their product's particular performance claims, as well.
The following information is an abbreviated selection of what is available in the crate engine marketplace, but at the very least it'll give you an idea of a fraction of what's available to us these days. Keep in mind as well that the crate engines shown here are by no means each company's full line of engines. For a larger selection and more info and specs I suggest visiting the website of each manufacturer for more detailed information on their offerings and to get the full scoop on individual engine specs and warranty information. Until then, take a look at the few examples I've gathered here-it may well influence your choice of powerplant, or then, maybe not ...

Their secret is simple-they transferred their years of racing experience into their parts. Through thorough engineering and extensive testing they've been able to assemble the perfect combinations of blocks, cylinder heads, manifolds, pistons, camshafts, and every other engine component used to produce the ultimate in power. The ICH 415-Magnum is the most recent addition to the company's broad selection of high-performance Mopar crate engines. The 415-Magnum is an ideal powerplant for your next classic Dodge pickup project. This muscular 520hp crate motor is based on a fully blueprinted Magnum block and fitted with a 4.00-inch stroke steel crank, Eagle SIR rods, Wiseco Pro-Tru forged pistons, Total Seal rings, a COMP Cams hydraulic roller cam (.580/.578-236/242 at .050) and a hefty 10.0:1 compression ratio.

Muscle Motors Killer Krate
This is the small-block version of their tried-and-true Street Killer Krate. This 440hp 500 lb-ft small-block is well mannered enough to drive across country, yet can be obnoxious enough to get the attention of the local sheriff if you care to misbehave. MM starts with 360ci blocks and performs full race-type prep. They Sonic check, align hone, parallel deck, bore, and hone using deck plates to ensure a precision-machined, durable short-block. They then install one of their pump gas, street 4-inch stroker rotating assemblies. This cast crank kit is cost-effective and is practically bulletproof under 5,500 rpm. The forged I-beams are lightweight and help these engines rev faster than a 340. Since these are "street" engines they choose a cam grind that works to 5,500 rpm, so they're great with a set of 3.23:1 gears. They finish filling the short-block with a COMP Cams timing chain, camshaft, and lifters. A Melling oil pump keeps everything lubricated and a Mopar Performance distributor drive and timing chain tensioner keeps everything timed properly. A new oil pan and pick up complete the bottom end. Up top they use the new Indy/RHS cast-iron heads and ultra low maintenance non-adjustable Mopar Performance rocker arms with10-degree locks, retainers, and dual springs. A dual plane, air-gap-style intake tops the block and makes sure this Krate has endless throttle response and makes tons of stump-pulling torque. All assembly information is recorded on a build sheet by one of their experienced engine assemblers.
The Top Krate
We couldn't help including MM's latest edition, the Top Krate. It may be a bit much for the street but man, it'd make a true killer classic truck race motor. With this baby they start with a Mopar Performance Siamese bore block made by World Products. They achieve 596 cubes utilizing a 4.53 bore, forged Ross pistons, and a 4.625 stroke Callies crankshaft. A Muscle Motors billet timing chain, dual line oil system and competition oil pan finishes up the short-block and keeps everything properly lubricated. Up top they use Indy Predator cylinder heads. These heads feature symmetrical intake and exhaust ports capable of flowing over 540 cfm after CNC porting. They actually have two proprietary intake port programs. The standard port utilizes a 2.400 intake and 1.850 exhaust valve sizes. The large CNC port program uses a 2.450 titanium intake valve. The small intake runner measures 440 cc, the large port measures 480 cc. The valves are actuated by T&D rocker arms that are available in 1.75, 1.80, and 1.90 rocker ratios. These rocker arms have no offset, which makes them very stable at high engine speeds. The standard Top Krate is also equipped with a single 4-bbl. cast intake manifold (2x4 optional) and sheetmetal valve covers. The single four-barrel Top Krate makes 1,150 hp at 7,400 rpm and 900 lb-ft at 5,700.
