Default Ignition timing chart xj12 1977 injection US spec

Anyone has a proper timing chart at 500-1000-2000-3000 & 4000 rpm for the PreHe US spec V12 (as well as one for the European V12 pre HE?) injection

Want to purchase the SNG Barratt DAB113HEF kit but it seems that it’s for a HE engine.

concerned about the vacuum/ centrifugal advance ratios of the different models Pre HE v12s.. and the HE v12s.. the SNG Barratt kit seems to be too generic.

This kit is for the pre HE engine and comes with new distributor and all required, so you should just be able to fit it and that is that.
