By subjecting a specific intake to rigorous dyno testing—comparing performance with the bonnet open versus closed—the true impact on air restriction becomes clear.

That iconic chop is impossible to ignore. This GTO Monaro might be running a more budget-friendly setup without the CNC heads, but the addition of the Turbo Killer cam completely changes the game.!

Clocking in an incredible 10.8-second quarter-mile time, this beast proves that you don’t need an endless list of major engine mods to dominate the drag strip.

The secret sauce? The Gmmotorsport Turbo Killer Camshaft.

This Monaro came to us with one goal: build a tough, reliable street car that sounds as good as it drives.

With a Harrop 2300 Supercharger, our GMMotorsport Street Racer Camshaft, and GM V3.5 CNC Heads, we brought that vision to life.

Every build is a chance to push ourselves and create something we're genuinely proud to put our name on. Hearing this Monaro come to life on the dyno reminded us why we're so passionate about building Holdens.

A huge thank you to everyone who trusts us with their pride and joy. We never take that responsibility for granted. 💪🏽🏁

The moment of truth arrives on the dyno! Swapping out an intake manifold for a CNC ported version often raises questions about real-world performance, but this back-to-back test clears the air.

Witnessing a milestone in automotive engineering as 'Lumpstick' officially enters the 500hp club! Despite battling barometric pressure drops caused by the rain, the team at GM Motorsport pushed this 6.0L L77 build to an impressive 505.5 rear-wheel horsepower.

It’s not just about the numbers; it’s about the build quality, featuring the legendary Chopper Reid Camshaft, CNC-ported heads, and the Rex Ramjet V3 intake. Seeing the difference a few tweaks can make—going from 500 to a solid 505.5 hp—is a masterclass in performance tuning.

The secret sauce starts with the infamous Chopper Reid camshaft—engineered not just for serious power gains, but to deliver that aggressive, choppy idle that car enthusiasts crave. When paired with a high-flow Ramjet intake for maximum air intake and a rowdy induction roar, the potential starts to skyrocket. But the real game-changer? CNC ported heads. By re-engineering the airflow dynamics, these heads turn the entire setup into a cohesive, high-performance machine.

Lumpstick Modlist Highlights:
* GM Chopper Reid Camshaft
* GM CNC Ported Heads & Intake Manifold
* Rex Ramjet (V3) Intake
* Rex Ramjet Triple Stepped Headers
* ASP Monster spark leads & pushrods
* LS7 lifters & LS3 valves
* PSI 1511ML springs
* Double row timing chain

🔥 Lumpy Fridays just got a whole lot louder... and whinier. 😏

This beast is running a Harrop 2300 Supercharger backed by a GMMotorsport Head and Camshaft package, delivering the perfect mix of tough idle, blower whine and serious power.

It whines more than the missus... and probably costs more too. 😂 But at least this one puts a smile on your face every time you put your foot down.

How good does this combo sound? 👇
