Holbay head

The SBH... number at the very bottom of the picture is likely the engine number... does it match the number on the block (RHS motor mount) or on any of the records?


Head over to lotuselan.net, lots of knowledge there about the Lotus twin cam as it was used throughout the Elan's life, including Holbay iterations.  Several there have access to extensive records and may be able to help confirm whether your engine was original to your car or, if not, what it may have originally been in.


You might also find the following article on the Lotus-Holbay of interest...
