Engine Blueprint Specs

I’m restoring a 53 XK120 engine and have been looking diligently for some engine blueprint dimensions. Originally I’ve been searching for the engine block’s main bearing bore diameter where the crank shaft lies, however, as I progress, I’m sure I’ll need more and more dimensions. Hence a blueprint, or similar dimensional spec list.

Where could I find these?

Happy to be here!

Do you have the factory Service Manual? There is a lot of information in there. It is available through the Jaguar Daimler Heritage Trust and other online sources.
