Chevy ZZ632 Crate Engine
Move over Mopar Hellephant, there's a new monster crate engine in town
A few years ago, Mopar launched a beast of a crate engine called the Hellephant. It was a supercharged 426-cubic-inch (7.0-liter) V8 that made 1,000 horsepower. Now, Chevrolet Performance has an engine called the ZZ632/1000 (an admittedly less fun name) that matches the Hellephant for power, and does so in a possibly more outrageous way: sheer displacement.
The ZZ632 is a big-block Chevy pushrod V8 – emphasis on "big" – that displaces 632 cubic inches. For the metric-inclined, that's a massive 10.3 liters, nearly 2 more liters than the displacement of the old Dodge Viper V10. Official output is 1,004 horsepower and 876 pound-feet of torque, the latter of which is a bit less than the Hellephant's 950 pound-feet. The ZZ632 also makes all this power on 93-octane gasoline you can get to your local gas station. It even revs to 7,000 rpm.

The engine is based on the same block used for the ZZ572, but with a sizable stroke increase and slight bore increase. It features a forged steel crankshaft with four-bolt main caps, forged steel rods and forged aluminum pistons, all packed into a cast iron block. It's topped with port fuel injection and a CNC-machined intake manifold.
Engines will be available through Chevrolet Performance dealers, and they go on sale early next year. No pricing was given. Chevy technically says the engines are for racing and off-public-road use, but we have a feeling some will find their way into some wild street machines.

Is there enough room under the hood of a Tracker for a V8?
The Trackers of that era were basically rebadged Suzuki Sidekicks, which were never designed for an engine like that. Not only that, but there is also the issue of a transmission large and durable enough for that kind of torque, which takes up even more room.Or are you refering to doing it mid-engine, like in the last post? The 2-door versions of that vehicle are so short that it might be difficult to do it even in that configuration.

There's enough room if you cut the front subframe and fab up your own.

god that would be amazing. I thought you were thinking of geo tracker, than I saw Chevy I guess made one too. interesting. Now that I think of it, would be really nice to have in a single cab truck. brb towing 20k lbs. 0-60 in 2.7 sec. need to re oil the differentials every 5k miles. LOL!!!!! Someone make this happen.

Chevrolet Performance ZZ632 crate motor MSRP is $37,758
Chevrolet Performance didn't price its 632-cubic-inch ZZ632/1000 crate motor when announcing the mill a couple of weeks ago. Instead, a Chevy dealer did the honors for us. As spotted by Muscle Cars & Trucks, Wisconsin's own Gandrud Chevrolet has the gargantuan earthmover listed on its GM Performance Motor page for $29,499. That, though, is the sale price. The MSRP, which GM Performance confirmed to The Drive, is $37,758. This brings us to an alternate meaning of "No replacement for displacement;" getting 10.3 liters of naturally aspirated V8 power for your hot rod is going to cost you another hot rod. And a tow vehicle, since this engine is for racing and non-public roads.
The funds buy modern engineering applied to old-school principles that run on 93-octane pump gas. The cast-iron block is accessorized with a CNC-machined high-rise intake, forged steel crankshaft with four-bolt main caps, forged steel H-beam connecting rods and forged aluminum pistons, spread-port cylinder heads, port fuel injection and overhead valves with a hydraulic roller camshaft. The resulting 1,004 horses and 876 pound-feet of torque should be able to fill the air with the stench of burning rubber, once a covetous hot-rodder has found the money to pay for the engine and a worthy car to put it in.
