I had an Edlebrock aluminum sixpack manifold done by them a couple years ago. It was one just before they started advertising the deep porting on their website, and it's documented in their articles. I have the numbers here somewhere, but it was averaged from 30 to 50 cfm per port over stock. The motor ended up putting out just over 680 hp at 5500 rpm. There is also a comparison to a 4 barrel on the site under the Dyno section, but not between a non-ported and ported sixpack manifold.
1970 Plymouth 'Cuda #'s 440-6(block in storage)currently 493" 6 pack, Shaker, 5 speed Passon, 4.10's 1968 Plymouth Barracuda Convertible 408 Magnum EFI with 4 speed automatic overdrive, 3800 stall lock-up converter and 4.30's (closest thing to an automatic 5 speed going)

They're expensive because it's all Hand Labor. To port a full range of manifolds and flow test them to market as Hughes is doing ![](/ubbthreads/images/graemlins/Twocents.gif) would be a huge undertaking. I applaud them for bringing this to the marketplace. Ex: I've been hand porting Holley Street Dominators for 20+ years because you can make them flow from about 270 OOTB to between 310 and 320, there's a lot of new manifolds out there that do that now but none i know of that will fit under a stock B or E body hood. With a high speed Carbide and a couple different bits I can do one in a little less than an hour, but that's only because the "CNC Program" is run straight out of my head from doing them so long. this is in part why only a very experienced head porter can still be cost competitive and still go toe-to-toe with what is typically charged for CNC work. But let's say if I wanted to entertain mass producing them for retail.... to teach someone else to do one would take a while at first and then I'd have to sell a number of them to get the skill up and the average time down make it worth while. Also there would be keeping inventory, some handling time, some samll factor for shop maintenence as well as QC/final inspection flow bench verification time,so even under best circumstances there's probably at least a few hours in delivering one back to a customer. And that's a single plane manifold, dual planes can be far more labor intensive as they have a lot more "nooks and crannies" and often times the 'dead flow' areas you need to wake up are the hardest to get at. For Hughes to do it Profitably they're probably figuring at least 4 hours of labor in each because they probably (I would think/hope) bench test them as well. There's a lot more to doing them right and devivering them to your door than a lot of people might realize. What would be helpful for them might be for them to publish the individual before and after #'s along with a recommended head flow/cam/carb app where their particular modified manifold line would best shine. The gains you can get from a well ported manifold can be pretty substantial and often times people are building motors with ported heads who'se power and torque are being limited (whether they realize it or not) by their choice of intake manifold. The choice is easier for Race motors because there are actually manifolds out there that can easily feed the port if you put enough carb on them and enough compression and carb that they can take WOT off the line with minimal pressure drop (which produces maximum torque and power). But on a street car to achieve maximum power up top a big flow race manifold may absolutely decimate part throttle torque to the point where your average torque/power in "real world" conditions can be down substantially, even though the motor may look impressive on a full throttle dyno pull. the real key to being happy with your motor project is to be 100% clear with what you want to have and conveying that to an experienced builder who can help you make the right choice of parts for your particular application. ![](/ubbthreads/images/graemlins/Twocents.gif)

There was some writeup in a magazine maybe 2 years back where a "manifold man" did all this stuff to increase intakes flow numbers. Then they dynod a bunch of his ported intakes and the improvements on the dyno just didn't jive what I was expecting from having seen what head cfm improvements alone can do.
That's probably because the ports in the intake manifold didn't make exactly the same pressure at the exact same engine speed as the intake ports in the heads.

... look at a fully ported Victor. It is really nice to look at and you can more appreciate the work that it takes to get one done.
Any chance you could post some images of your ported intakes (a Victor 440 would be a good choice )?
Also, can you pass on any "real world" results on the dyno and / or track from customers who have stepped up to your ported intakes? Any info you can provide is appreciated. ![](/ubbthreads/images/graemlins/bow.gif)

BTT (again)... hoping for some feedback from the Hughes rep.
Have you tried giving them a call?
