    Please note: Where a customer supplies their own engine for reconditioning or modification, we will use that engine and its components unless there is a defect or fault that does not allow for a rebuild. At this point a suitable like for like will be used from our core stock. For 1275cc based applications, We have MG Midget / Austin Healey Sprite and Morris Marina core units. For reconditioned standard road units, unless otherwise requested we will just pull the next core from stock. For our GT and RS packages we will pick the next cores that are either Standard or on their first oversize and will be built using EN16T Crankshaft. Race applications, where the regulations require a specific engine casting we will build using that exact casting, where the regulations are open with engine variations, we will build using the next cores that are either Standard or on their first oversize and will be built using EN16T (or where applicable EN40B) Crankshaft.

    If you have an exact requirement, please specify at the very start, make it clear. What ever the application, we will pick the most suitable core and machine to exacting standards, you will receive the very best engine for your application. That's an MCCS promise.

  • 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.

  • Surcharge and Payment

    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 £600 (for large bore engines) surcharge that will be applied with your final payment.

    Engine Payments

    If you have found the engine that you wish to purchase from MCCS, you can place your order online or we can create your order for you. 

    To secure your build slot, We only ask for £100 upfront. Once we have completed your machining we then take 50% of the remaining balance (we do not store payment details so we make contact with you at this point) We then complete the build and only when complete and ready for you to collect do we require the remaining
