I agree 100% on that peter Is a perfect combination for a L series just weigh a bit more, I love the external pump adjustment, Taper Bore, I stuck a bore camera down the venturi and you could see the piston, I was lucky to find 5 sports 2000 carbs and managed to find three good bodies as they are soft , On a flat top piston L28 with a E31 head Les built for me when he was at Datrally, Tony helped me make up a intake manifold from a L4 Datrally manifold we cut it in half and Tony had the centre intake runners cast to suit 3&4 cylinder and we bolted it to the head matched ported it dowled it and welded it all together with the 44phh rose joints on all the linkages . Could be heard in the pits at sandown full noise across the back straight and everyone would say to me, " I didnt know Datrally made a 6 cylinder intake manifold" they dont, but the person who was making the Datrally intake manifolds in NSW Died an the foundry shut down , so I have a very unique intake manifold and is still on the same engine since 1993 and still goes hard
