The Speedmaster 355 Holden crate motor addresses a clear need in the Australian performance market: a complete, assembled engine ready to install. Built by Sydney Speed Supplies using Speedmaster components, this 355 cubic inch Holden combination arrives as a turn-key package.

A Complete Engine Package

The 355 Holden crate motor is not a collection of parts requiring assembly and setup. It is a finished engine, built with matched Speedmaster components from the rotating assembly through the top end. Cylinder heads, intake manifold, camshaft, and valvetrain are selected to work together, and the engine is assembled to specification before it ships.

Built for the Holden Platform

The Holden V8 has a dedicated following in Australia, and finding quality components for a reliable performance build can be a challenge. The Speedmaster 355 package solves that by providing a complete engine built specifically for the platform. Whether it is destined for a street car, a Torana, a Commodore, or a dedicated race vehicle, the 355 delivers a proven combination out of the crate.
