Every engine that enters the shop gets measured before it gets opened: compression, leak-down, oil analysis, and a cold-start recording. Then we pull its original build sheet from the archive — or reconstruct one — and only then does a spanner touch a fastener.

What the numbers can’t tell you

Compression tells you what a motor is doing today. The blueprint tells you what it was built to do, which tolerances have drifted, and how much headroom is really there for more power. Skipping that step is how 300-horsepower dreams become 150-mile engines.

It adds roughly forty hours to every build. It has also meant that no GRANDSTAND engine has ever come back.
