Chevy Performance has created a 1,004 hp crate engine

Well, this is neat… If you like monstrous big block beefy boys, Chevy has (and has had) the engines for you. And now there’s a new king. Chevrolet Performance is bringing a monster to SEMA and it arrives as a 632 cubic-inch V8 that produces 1,004 horsepower and 876 lb-ft of torque.

It’s called the ZZ632/1000 crate engine. Chevy should just call it Sir Strokes A Lot or something else ridiculous because that’s what this thing is… and Chevy will sell every one it bolts together.

This beast uses an iron block similar to the one used by the also mighty and large 572 crate engine. But here the casting is machined to accommodate the extra displacement. You have a longer stroke, high-flow aluminum cylinder heads, equal length cylinder ports, and an entire package that produces wicked power on pump gas.

It will likely cost a ton of dough. And it will also likely make some drag racers very happy. And the one maniac who shoves this into some otherwise stock-looking street car. We salute all of you on your respective journeys.

    I know an appropriate place for one.

    632 C.I. is 10.36 litres in the rest of the world. That’s getting up into WW2 aircraft engine capacities.

    The ideal engine to do a ‘restomod’ on an Iso Grifo 7 litre, swap one big block for another, plenty of room under that ‘bulge’.
    And probably best to swap those Borrani wire wheels for some alloys.

      There’s no such thing as a 10.36 liter engine in the rest of the world. In metric, 632 cubic inches converts to something like 4.4 twinturbo liters.

        Got to say, Europeans have all but abandoned 10 litre engines for trucks…

    Wow, 100hp per liter….that is ’60s tech.

      Torque translates to 1165 Nm which is pretty good by modern production engine standards – presumably there will be some fine print somewhere stating what exhaust is needed to achieve that, and hopefully that will fit in actual vehicles!

      Also torque peak at 5000 rpm… usually such an engine will be called a torqueless wonder LOL

        Surely not with a torque curve as flat as that, 600 lb/ft at 3000rpm is 50 % more than the peak torque of Mercedes Benz’s torque monster, the old 6.9 V8 in the W116 450SEL of ‘Ronin’ and ‘C’etait un rendezvous’ fame.
