Hey Chris,
Did you mean for this to go to the list instead of just me?

Either way, I?d like to clarify the veracity (truth) about the hump in the words I find to be most accurate. 
?I fall on my face EVERY time I try to leave the driver?s seat on a coach with that %$@# hump. I hate those things.? 
Seriously, I Really ?Really HATE THOSE THINGS !!!!

As for port injection, I love the idea, but I?m not that good. I?m a kit guy remember? And I?ve not installed a port kit for these GMC?s. Having said that, I do know of a GM OEM port manifold that came with a later year OLDS 403. I know of one gentleman that is using that cast iron monster with the Dynamic EFI board in his 7747. One of the new low profile aluminum intakes also has bosses cast in place to be machined for injectors at the intake ports.

OT?
Eldorado or Toronado Hubs are easy. Try to find a GMC hub in a junk yard! Sorry, couldn?t help myself.
Yes they can do Eldo?s and Toro?s. And they are willing to machine a tighter tolerance at your request.
The company we use is 
Columbus Col-Wed
1515 Harrisburg Pike
Columbus, OH 43223-3609
(614) 276-5303
They have grown to the point that the side business of supplying engine rebuilt parts is now larger that the parent welding / machining company.

I question the veracity of the owners statement? 

If you are retrofitting EFI, why leave the manifold wet, if that?s a problem? A few hundred bucks more to go port injected, and no hump in the floor. I fall on my face EVERY time I try to leave the driver?s seat on a coach with that %$@# hump. I hate those things. 

But onward ? very OT, but I would be really interested in getting the contact info for the shop that fixes the hubs? Good ones in junkyards are getting scarce, and I?m betting that they can do the same thing to an Eldo hub ?
