427 Cube LSX Pre turbo test! What power will it make?

Check out this Big Cube 427 LSX Chevy torque monster built by the team at PowerHouse Engines. But there is a twist with this one, as it's been built for turbos and we decided to test it without them first to see what we sort of power could make! The LS1, LS2 and LS3 engines have massive potential and this test is proof that you just can't go wrong with this iconic Chevrolet engine platform if you have the know-how!
At Master of Machines, we love cars, in fact, we love anything with wheels or an engine, from American Muscle Cars to Australian Muscle Cars, Race Cars and Classic Cars of all kinds and even Barn Finds. If it's fast, powerful, restored or hidden away in hibernation then we'll cover it, and in most cases, we'll even drive them!

Love that high RPM scream! Nothing else sounds this good. 👍

That's some serious power na with low compression ! Can't imagine what it'll do with the turbos ! Thanks for a great video.........

[@CathodeRayNipplez]

WhaTha? 620hp on low compression and no boost. What a weapon.

Wow... very similar build just with 11:1 cr. I estimated it to be about 650 na. Im wondering if its actually a bit more. Thats awesome info guys.

What a monster

[@THROTTLEPOWER]

I agree!

[@jimclarke1108]

7000 RPM, LSX 7 Litre, as good as it gets

[@samperras]

There’s some investment

[@79tazman]

Not bad for as low compression it has you could run 87 octane in that thing myself would want at least 10.0:1 compression but that's my preference

[@colinstewart1432]

Aw man, that howl is tasty 🤘

Buried that 408 Ford Cleveland
