We are offering New Pre War Cats Paw engine castings in LM25FT.


These are offered as a fully machined item, and we pride ourselves in offering a fully joined up service.  That is, you supply your crank and sump to us. We then machine the New  Pre -War style Crankcase to match exactly to your sump. Then we fit the engine with shells to take your crank and ensure that all the rotating parts work correctly as they should.


You receive a completed job that is ready to be built....no more having to get the half CNC machined Block that then need fettling to actually fit your parts.

Included in the price we modify your crank for a Modern Rear lip seal and this is also accommodated within the engine.

All this for a total cost of £5,500.00 ex-Works....Extra for 4 bolt fixing main bearing caps and any crank grinding.  Any crank can be fitted with shells into the New Engine.


We also do Water jacket replacements and Oil Pumps along with precision made central Oil pickups,  all as extra or mods to any engine.



Lightweight Dynamo and alternators can also be supplied to order. Alternators can disappear into a dummy shroud if needed. Please do ask for more details.

AC Light Weight Flywheel. original is 14.2kgs. New 5kgs


£625.00 ex-works.  Supplied to order, to suit your crank.

These Brooklands Enginecraft AC 2ltr. Racing flywheels have been made to weight as little as possible.

Thus when fitting the starter motor it may need fitting in a slightly different position to take account of the shorter ring gear width.

This may involve some machining of sump or starter motor to achieve best fit for purpose.

Please ensure your engine builder is aware of this before building engine with these items.
