Stacey’s PHAT WN Caprice just got a whole lot fatter 😮‍💨🔥

We’ve just finished this one off with a pretty unique setup - a Harrop 2650i paired with an LS9 supercharger lid, custom fitted to work together.

The full setup included:
• Harrop 2650i supercharger
• Custom-fitted LS9 supercharger lid
• Forced Induction Interchiller kit
• Cam package to suit
• Upgraded injectors + supporting mods
• Tune

A heap of custom work went into making everything fit, function and look like it belongs there.

Safe to say PHATWN is living up to the plates. 😏

Another VL build wrapped up at All GM Automotive 🔥

This one came in for a serious overhaul, with the setup rebuilt and reworked from front to back:

• Complete engine rebuild with fire rings
• New convertor to suit the new combination
• Custom dump pipe, intercooler and intake fabrication
• Custom brake lines
• Catch can modified to suit the new setup
• Custom fabricated upper radiator hose to suit the new plenum
• Engine bay clean-up
• Tune to bring it all together

Plenty of work went into getting this VL sorted properly and making sure the whole package works together.

Another tough build out the door 👌

Proud to be supporting Holden Drag Nationals again this year! 🏁

We’re working around the clock to have both the VN and HQ ready for the event. See you all at the track! 🔥👊

Another fantastic sponsor has been confirmed for the 2026 Holden Drag Nationals. Terry and the team at ALL GM Automotive have been long-time supporters of the event, both as competitors and sponsors, and we’re incredibly grateful for their ongoing commitment.

We’re hoping to see Terry’s billet LS-powered VN Wagon making an appearance at the Nationals. The team has been flat out preparing the car for Street Machine Drag Challenge, so we know they’ve got plenty on their plate.

Fingers crossed the wagon is ready in time and we get to see it hit the track at the event! 🏁🔥

A little behind the scenes…. 👀🎥Any guesses what the next video is about??
