Anyone know of a resource that defines the engine serial numbering code for the C-series engine? I'm familiar with the 29K engine used in late Austin-Healey 3000s, but the engine of interest has the following serial number:
29AW/PC/H19748.
If you can help to interpret this number, please respond directly to me at the address below.
Thanks!
