James. Sounds like you know more about it all than i do, im not familiar
with the LH2.4 . I guess the problem with be, as someone else suggested, in
the throttle transitions. But if it is a clever system it may well overcome
any problems. You sound pretty brainy so dont listen to my negativity, go
for it. As for the manifold being expensive to make, dont rule out the
single butterfly and welded steel manifold setup, very cheap as you can just
pick up a butterfly from a wrecked car.
Some links for you, this guy has the best bookmarks page ive ever seen.
Check the Winbin and Tunner Cat pages for info on the delco software.
