Have you tried VPW in Vic yet? They seem like a smaller version of Summit. Try the link here for the Edelbrock Performer manifold.

I think you're talking about the Roush intake made for 94-95 Mustangs. Had an air filter that faced the rear to feed cold air from the back of a cowl hood. They were running them out some time ago from memory and no longer list it on the web site but I think I have a photo saved somewhere if people want a look-see. Very trick looking I must say.

What is your planned combination, ie heads, displacement and intended usage? Be honest about this because the wrong intake can kill low end torque/power if you go too short on runner length and/or too big on the runner width. Re the usage consider rev range it will be designed for and also whether forced induction will be used.
Hmm say, you're running a 347 stroker now right? If so look at the Edelbrock Performer RPM, TFS Street & Track Heat or the Holley Systemax (now Weiand Stealth). The Holley does have to run with tb on the other side though due to the assymetrical port layout where upper and lower meet, a la Truck 302/351. All these should suit pretty well.
Of course if you still have wads of cash burning a hole in your pocket consider the BXR unit like that Perth guy put on his wild TE50.
