Factory Options 1969 Lotus Seven S3

Does anyone know what the factory options were when purchasing a 1969 Lotus Seven S3? I have a barn find that the owners son has reported once seeing the bill of sale....and it included two options. I think one was $35 for a heater, and the other option was $100 for some engine/drive train change. Does anyone have any idea what the $100 option on drive train/engine might be? Car originally cost $1500 in 1969 apparently, and I believe that was for a completed car

I guess I am a dreamer. Any idea what the uplift for a Twin Cam engine would have been for a Lotus Seven SS?

The S3 Seven came with 2 engine tunes. The base was the crossflow Ford Kent with a single downdraft Weber and compression ratio of 8.3:1. The upgrade, which is most likely the $100 extra, is the Cosworth tuned engine with 9.5:1 compression and dual sidedraft Weber 40DCOEs and headers.

Cheers,
