Welcome.
I owned a 1967 Lotus Elan S3.. great fun..
I assume yours is a late model...
Looks like a 72.
Spot on! A late big valve 5 speed. 1972 Lotus Elan +2 S 130/5 to give it's full title.
I've been out in it 4 times and it has broken down twice because of the poor work and neglect of the "professional" restorers.
I'm nearly there with the engine rebuild. (timing the twin cams!)
