How much HP can you get out of a LS7?
You’re safe for up to 1,000 horsepower on the factory LS7 block, and a naturally-aspirated build is unlikely to challenge those limits. If you want to add some insurance on your way up to that limit, however, you’d do well to invest in forged pistons once you’ve crested 700 horsepower.
How do I get more power out of my LS7?
The LS7 makes over 500 horsepower naturally aspirated right out of the box. As good as it is, racers and the aftermarket love this engine and tons of great parts are available….Basic Bolt-On Upgrades for LS7
- A cold air intake.

Can you boost an LS7?
Blocks don’t care about boost. They care about cylinder pressure. I could get a ls7 block to hold 40+psi if needed by putting some stock ls1 heads on it, restrictive intake, and only make 600rwhp on 40psi. Boost does not matter at all.
How much nitrous can a stock LS7 handle?
Registered. The shop that built my LS7 stated stock pistons limit nitrous applications to 100 shot.

Does the LS7 have forged internals?
The pistons in the LS7 are cast hypereutectic, not forged.
How much boost can a LS7 take?
While the amount of boost that a given engine can run is a less than steady mark, it turns out that you run the risk of bursting your LS7 intake manifold if you run more than 26 psi.
How much is a LS7 crate motor?
By ditching the LS7’s dry-sump in favor of a traditional oil pan without any exterior lines or plumbing required, the LS427/570 should make engine installation that much easier. The LS7 is currently priced at $14,837 according to Chevrolet Performance, whose website notes that there are limited quantities available.
What year LS7 have valve issues?

Are LS7 intake manifold and throttle body worth it?
These upgrades are great for a naturally aspirated engine running pump gas. The LS7 intake manifold and throttle body work great on a stock engine. However, if you want more power, you need to feed the engine more air. The stock intake will be a restriction with a big cam and high flowing heads.
How hard is it to get an LS7 to turn stratospheric rpm?
Getting an LS7-based engine to turn at stratospheric rpm numbers is no small task, but the students and staff at EFI University put themselves to the challenge for project they dubbed “Spinal Tap.” This project engine is being built for 11,000 rpm (it goes to eleven, get it?) and is ultimately destined for the drag strip.
