Morning Graham,
I don't think John reads the MessageBoards - he's not a big fan of the computer thing but you may want to get intouch with him - his details are in The
Courier (won't post them here). He's the Spitfire MkIV/1500 Registrar and his contact details (club email) is listed on the Club Officers page
here.
But, (and I wait to be corrected here) isn't the Vitesse Mk2 engine the same as the GT6 MK2/3 engine? If so shouldn't that stuff bolt on (providing
there's room under the different shaped bonnet).
I know one of the racers has the triple SU set up on his Mk2 GT6 and he's looking for a triple Weber setup. So when he find one I expect he may have a
set for sale - so they do crop up from time to time.
Cheers
NiG
