Built around your car

Not every LS1 needs the same cam

Camshaft choice affects idle quality, low-speed behaviour, torque delivery and top-end power. We consider the gearbox, converter where applicable, diff ratio, cylinder heads, current modifications and intended use.

Oztrack GTCamshaft fitted

This vehicle includes CNC-ported heads, a FAST 102 mm intake and other upgrades beyond the base OZ365 package. It is a real higher-spec LS1 example, not a guaranteed OZ365 result. The approximate 365 kW OZ365 claim is engine power; dyno measurements are a different basis.

Camshaft selection

Choose the right Oztrack camshaft

Final selection and piston-to-valve clearance depend on the complete engine combination.

Comparison chart for Oztrack LS camshaft options — Oztrack LS camshaft comparison guide.

GT — factory-piston option

A cathedral-port LS1–LS2 cam that can suit factory pistons where the heads have not been shaved and measured clearances are suitable.

GTX-R and HPX-R

These larger cams require aftermarket pistons with valve reliefs, or suitable flycuts machined into the factory pistons.

Want one of the largest cams? Oztrack can supply replacement pistons with valve reliefs that work with factory connecting rods for suitable combinations.

Before you book

OZ365 LS1 questions

Is 365 kW measured at the wheels?

No. OZ365 refers to approximate power at the engine on a healthy combination. It is not a rear-wheel figure or guaranteed result.

Will it suit every 5.7L LS1?

Suitability depends on engine health, cylinder-head machining, transmission and existing modifications. Contact us before ordering.

Can I keep the factory pistons?

The GT can suit factory pistons where the heads have not been shaved and clearances are suitable. GTX-R and HPX-R require valve reliefs or flycuts.

What if I already have a good exhaust?

You may be better suited to the separate cam upgrade and ProHub tuning package. We can assess the parts already fitted.

How long will Oztrack need the car?

Allow approximately five days for a typical installation. We confirm timing when booking.

Is finance available?

Yes. Ask the team or use the finance section on this page.
