When it comes to engine performance, most people focus on the big-ticket upgrades — intake systems, exhausts, camshafts, injectors and ECU tuning. But one part that is often overlooked is the ignition system, particularly the spark plug leads. For a V8 engine to produce consistent power, the ignition system needs to deliver a strong and reliable spark to every cylinder. If the spark isn't consistent, the engine can suffer from misfires, poor throttle response and reduced perf

If you own an LS3, particularly one fitted with GM 0821 cylinder heads, there is one issue worth knowing about: valve seat failure. What can start as a relatively small problem inside the cylinder head can quickly turn into major engine damage when a valve seat comes loose and drops into the combustion chamber. We recently had an LS3 come into the workshop after suffering exactly this type of failure. Watch the Full Video Breakdown In the video below, we explain what happened

All the best components under one roof! 🧰💪 This Holden VE V8 came in for a serious upgrade — and we made sure it left as a true street dominator. The owner had previously undergone a DOD lifter replacement at another shop, but after just 10,000 km, those lifters failed. Rather than risk another round of the same issues, he chose to do it right this time — opting for our Texas Speed Cam Package, designed for both performance and longevity.
