- Brand new cylinder block cast in Aluminium LM25TF and machined in house at SAS Engineering
- Nikasil plated and diamond honed to 90.335mm.
- Supplied with solid steel caps with dowelled location and our high quality stud kit with rolled threads for increased strength.
- Originally machined from genuine Cosworth castings, we have now remanufactured the patterns to the same standards as the originals but with improvements to reduce porosity, improve mould flow and casting solidification.
- All plugs fitted and pressure tested prior to dispatch
Due to the number of different specifications/configurations of cylinder heads and blocks on offer, we do not hold large amounts of finished stock. Therefore there is typically a 3-6 week wait for these items, if this does not meet your needs please get in touch prior to placing an order.
