I don't think it'd be that easy. I saw one made with a roots blower on top, and it was novel, but I don't think it would be very easy to fabricate.
I'd probably start with mandrel-bent header primary pipes and weld them to a common plenum above the valve cover. On top of this plenum would mount a 4 bbl carburetor. It would be an interesting experiment and would probably run reasonably well. But frankly, I think I'd get a lot more power out of a turbo using the stock intake because it would be force fed.
MoneyPit, I'll contact you in the spring. I'd really like to see your truck, and I'm anxious to see how a built stovebolt runs.
Thanks.
