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.
