Lynn, I use 1/4" vacuum hose to the plenum, MAP etc. Attch. is the only picture I have, not very good but it gives the idea. I also use 1/4" steel pipe (inside) that connects to the IAC motor with it's own neat little air cleaner, all hidden inside/under the rails/throttle bodies.
Ron, the previous thread about HIGH RPM power ( you were looking at track applications, with >7000 RPM peaks) went into some depth re. limitations of the 8 stack systems. I'm too lazy to dig up my automath book, but as you say, a 340-350 cube engine requires a lot of air at 7500 RPM. The equivalent individual throat diameter would have to be pretty big, which then introduces air velocity problems at low RPMs. I guess you could do it on a full race motor, but I would think it would be a royal pain in the butt to drive on the street?
