Do I only require a Short Engine?


The short engine is often purchased as a replacement unit in situations where the cylinder head is serviceable. Before installing this newly built unit, it is a good idea to question what made the original fail. A couple of common causes of bottom-end failings are;

  • Incorrectly set carburettor, Bore wash is a very common cause of bottom-end failure. This can be caused by a carb in need of an overhaul or by the mixture being set incorrectly. The bores glaze causes poor pressure readings but also allows fuel to then breach the rings and dilute the oil.
  • Incorrectly set timing. Another common cause can have catastrophic results.


All of the engines that we build are built using new components throughout, this ensures that whether you are purchasing a Short-Engine or a full Stage 3 Road Engine, you get peace of mind that the engines are built to the highest standards using all new, quality components. We stand behind our warranty with pride for our work.

    Engine Surcharge

    This engine is sold on the basis of having an exchange unit returned to us or working on your own unit. If you do not have a unit to supply us with this is not a problem however there is a £200 (for small bore short engines) surcharge that will be applied with your final payment.

  • Time Frames and Shipping Info

    We always try to give an accurate and honest time frame for your engine builds, being in control of the machining and build has allowed us to monitor the times with the only out sourced aspect being the testing.
    Due to the successes our race clients are enjoying with our engines along with the consistency of our Road builds, we have found our selves picking up a lot of new Race clients along with supplying some of your favourite classic car specialists both domestically and overseas. With this comes pressure on us to meet the demands from these sometimes time critical builds. We have therefore taken the decision to advertise our road builds on a 6 month build plan. If this looks like it may increase we will let you know at the first signs of it. Last year was our biggest year for trade and Race clients, we have a small team here but we trust each other and know the quality we work to.

    The 6 month build plan is based on all of our set engine packages. Builds that are bespoke to your requirements may take longer.

    Race and Trade clients please contact us before ordering.

    We have removed shipping from the website checkout due to the ever-changing shipping rates for such large items.
    We use wooden shipping crates for international orders and restrain the engine for secure transit. Please reach out to us for a quotation for shipping your engine.
