Hi All,
Most of my mods were written-up in a Magazine article published in the XJS pages in the Sept 2014 edition;
https://jec.org.uk/magazine/vol-30-no-09 (page 45 onwards). Since then it has "benefited" from blingy gold wheels

, a brace kit, AJ6 eng. TT extractor exhaust with twin tails, AJ6 enj. intake tuning pipes, HB front anti roll bar upgrade, super-blingy blue 3 ply silicone hoses, HT cables and a new distributor cap as well as regular servicing and attention.
The run up Prescott Hill that David is referring to was captured with a couple of cameras; some footage here (edited to start after my poor music edit

);

In terms of just the manual conversion, it was a 70 hour project. However, the chap (David @ Alders Classics)
http://www.aldersclassics.co.uk/ has performed a number of these conversions now, so likely to be less than 70 hours now.
I hope to be attending JEC events this year with the Cat so if you are around look me up...
Cheers, Rich
