Big-Block Crate-Style Engines - Power To Spare
0408 MOPP 01 Z BUY

For some, the ritual of hauling a grease-encrusted engine in the trunk of their car to the machine shop is something to look forward to. It's a new lease on life for a tired engine, and the promise of more power and better performance. For others, it's a ritual requiring time, patience, and even more time. Add the pressure of finding a machine shop you can trust and won't soak you for unnecessary "additional" work, and it may be a dreaded experience. But what else can you do? What if you don't have the time, desire, or mechanical know-how? It's quite simple to opt for a crate-style engine. It's easy to choose an engine package that is already assembled and scienced-out, delivering a proven package.

We've assembled a gathering of big-block crate-style engines from a number of manufacturers and limited the price ceiling at $10,000. we even threw in a couple pieces at slightly over the ceiling just for comparison's sake. While this may seem somewhat steep, add up the cost of all new parts and machining, and you may find a crate engine is a bargain. And you won't have to borrow your neighbor's truck and haul a greasy lump of cast iron to your machine shop.

Mopp 0408 02 Z+big Block Crate Engines+mopar Performance Engine

Mopar Performance
The Mothership got in the crate-motor racket a number of years ago, and has come up with a number of good crate engines for predictable performance levels. Mopar Performance offers everything from mild small-blocks to stroker Hemis. The most popular of the big-block wedges are these two examples. It is important to note that these engines are built from all new components. For a mild-mannered heavy vehicle, the 500-inch wedge makes a lot of sense. It'll move with authority on a steady diet of pump premium, but with nearly 600 lb-ft of torque it will melt the tires at will. The 500ci short-block assembly is a great foundation from which to build a torque monster or a high horsepower producer-the choice is yours.

Mopp 0408 06 Z+big Block Crate Engines+hughes Hensley Perofrmance Engine

Hensley Performance
Hensley Performance has been in the Chrysler engine building business since 1967, and features a full-service, in-house machine shop run by Matt Hensley. If that name doesn't ring a bell, Matt's SS/AA '68 Hemi Cuda recently ran an 8.74 at 154.78, the highest trap speed ever recorded by a SS/AA racer. The list of available crate engines and options is mind-boggling and competitively priced to accommodate a wide range of enthusiasts. We believe the Hensleys are more than qualified to handle your engine-building needs. How about 493 ci of tire fryer? The Hensley 493 will deliver a good blend of streetability and muscle-packing dominance for the track. Need something a little more...shall we say...dominating? Although the 451 Bracket Buster gives up a few cubic inches, the added ponies kinda sneak up on you and the guy in the other lane.

Muscle Motors
Muscle Motors of Lansing, Michigan, has been in the Mopar engine building business for 15 years. Their services include complete crate engines, as well as custom builds and rotating assemblies for popular stroker applications. Appropriately dubbed the Killer Krate by the good folks at Muscle Motors, this 496-inch fat-block delivers the goods in spades, all on available pump-premium. A recent example punished the dyno to the tune of 626 horses and an axle-snapping 640 lb-ft of torque. More than 500 lb-ft of torque is available from a basement level 2,200 rpm all the way through 6,500. As if that wasn't enough, this thing is packing a maintenance-free, off-the-shelf hydraulic cam. In a decent chassis, this combo should be good for deep tens all day long. A complete Killer Krate from pan to intake can be yours for $8,999. For just over $10,000, you get a turnkey crate with carburetor, distributor, wires, plugs, and oil that's been broken-in, dyno'd, tuned, and ready to rock.

Hughes Engines
Anything Mopar you need is more than likely lurking between the pages of the Hughes Engines' catalog. Dave Hughes has been in the Mopar engine building business for close to 35 years and was one of the first to promote and take advantage of the .904-inch lifter diameter, recognizing the fact that Chryslers have a unique advantage in the realm of camshaft profiles. We tapped into Dave Hughes' vast inventory of crate engines for these two fine examples. It is important to note that Hughes' offerings are all "custom" crate engines, leaving the customer the option to outfit his crate in any manner he or she sees fit from aluminum cylinder heads to max porting to hairy solid cams. Plus, all engines will be assembled to specific specifications based upon customer use, including altitude, camshaft profile, and available fuel quality (octane). Price requires customer-supplied core (block and crank for the 440; block only for the 500-incher), but includes start-up and break-in.
