Reply to "Weber IDF's and Panteras"

Can't really comment of the IDFs. No experience with them at all.
Considering though that the Australian manifolds are for iron 2v heads, I'd say there are no manifolds for the 4v's.
My thought is don't run 2v head stuff unless for some reason you have to.
Port flow on the newer "good" aluminum 4v heads is 330cfm ish. Do those Aussie 2v manifolds flow that? I doubt it? Look at the ports.
As it is Hall's manifolds for the 4v and SVO are the only two really available.
I heard Falconner & Dunn had built one, but one of them 10 years ago said, no, they never had.
I suppose if you can weld, you could make a sheet metal manifold for the IDFs on a 4v I suppose?
The IDAs really are streetable. There isn't much to be gained by running IDFs?
The IDA transition "issue" can be minimized by adding a third transition hole in the carb.
Still there, but almost gone.
The issue for me with Webers on the Pantera is you can't wssh the car unless you cap the velocity stacks. PITA. What do you do if it rains with them? Instant water injection?
