Smallblock intake manifold shootout.

I've had my Weiand accelerator about 5 years. It started on an old 318 build then ran on a 360 for 4 years. Got my old Dart into the 12.9's. It is on my new 340 in my Duster now but I just got a good deal on an RPM Airgap and wondered it it is worth changing it out. 5HP I am not going to sweat, but if I am giving up 10-15 in TQ it is probably worth thinking about.
