i thought a modified 20vt manifold may be almost an equivalent but still only single t/body
stu - dunno if they are big enough (45?) but i have a bare set of dellortos with just the opening flaps in em if you want them - used similar on a pinto recently just filled/cut everything out and added sleeves for the injectors a bit like t/bodies but only 2" tall - has 4 more injectors sat out side in the airbox housing now to
help out top end
iirc- the centres slide out and is 48mm inside anyway
anyone tried motorbike sliders yet ?
