When i worked at the Jag radford engine site back in the 80S there were 3 V12 engines built that were
7LTRs with Warrior 5 valve cyl heads i was told these made 700 hp on the dyno
Its said these engines never ran but i know they did as
I know the whereabouts of 1 engine and its pushing an xjs along,
I also built 2 4ltr straight 6 twin turbo engines which were put in police xjss
All before camera phones :-(
