Big day at All GM Automotive!

Our new lathe is set up and ready for all those little machining jobs!

We’ve also had our BlueCarve CNC plasma cutter running for a few weeks now, making custom brackets, catch cans/tanks and more.

Another step towards keeping more work in-house and taking the quality of our builds to the next level!

With the opening of victorianmotorsportspark coming up, along with events like STREET MACHINE Drag Challenge and other events, we’ve been getting increasingly busy with IHRA technical inspections and logbooks.

During these inspections, we’re finding quite a few of the same smaller requirements being overlooked, so here’s a few things worth checking before bringing your car in.

* Roll cage padding: FIA 8857-2001 or SFI 45.1 padding required anywhere the driver’s helmet can contact the cage.

* Tailshaft loops: Required on many modified, engine-swapped and boosted RWD vehicles. Generally mounted within 150mm of the front uni joint, with 360-degree enclosure.

* Transmission cooler lines: Proper transmission-rated hose and fittings required. Rubber fuel hose is not permitted.

* Wheel studs: Must protrude beyond the wheel’s outer face by at least the stud diameter, with thread engagement into the nut at least equal to the stud diameter. Open-ended wheel nuts required quicker than 11.00 seconds.

* Engine containment: Boosted or nitrous cars quicker than 9.00 seconds (5.70 eighth-mile) require an engine diaper, suitable belly pan or equivalent containment.

* Oil catch cans: Supercharged, turbocharged and nitrous combinations quicker than 9.00 seconds (5.70 eighth-mile) require a minimum 4L breather/oil tank. Breather hose volume doesn’t count towards capacity.

* Cooling overflow: Minimum 600mL catch can where the system could discharge liquid onto the track.

* Battery isolation: Where required, the external cut-off must shut down the engine and all electrical systems, including the alternator.

These are just some of the smaller things we’re regularly checking, on top of cage construction, brakes, steering, suspension, fuel systems, driveline and driver safety equipment.

Requirements vary depending on vehicle construction, class, ET and MPH.

If you’re preparing a new build, need an existing logbook updated or want to make sure your car is ready before the upcoming events, get in touch to organise an inspection.

QUICK WORKSHOP UPDATE 🤒

Unfortunately, Influenza B has made its way through the All GM crew over the past week, and we’re currently running a little short-handed while everyone gets back on their feet.

We know there are quite a few of you waiting on quotes and replies to enquiries - we haven’t forgotten about you! We’re working through everything as quickly as we can, but responses will be slower than usual.

All current bookings are still going ahead, however there may be some delays with turnaround times while we’re down a few hands.

We apologise for any delays and really appreciate everyone’s patience and understanding while we get the crew healthy and back to normal!

Thanks for bearing with us 🧡

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

• 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

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

Another tough build out the door 👌

Our part’s done - now it’s off to paint and panel.

Keen to see this thing finished and back together! 👌

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! 🏁🔥
