Lotus Twin Cam "L" Block race prepared. The most common requirement for these precious Lotus blocks is for them to be prepared for serious competition. Usually finished at 83.5mm (.+040) with square cast iron (crossflow) or steel main caps. This spec involves more often than not linering the bores back to satisfy the 83.5mm size and line boring the stronger main caps choice. We opt for the short jackshaft so we install new cam bearings with the rear one used as a blanking off piece. The blocks are crack tested at the outset, acid cleaned and washed out after the machining process. Obviously the oil galley plugs are removed initially. Now and again we can supply a block that does not need liners or main cap modification so there is a savingto be had, you must call for details.
Price quoted is for linered, steel main cap block that is undercoated and ready for assembly.
