I'll measure it up for you John. I never fully figured out the Ramcharger style setup as I changed cars to a 66 before I ran the setup on my 71. On my 66 the Holley float bowls are too long and you cannot use the stock filter in any way, so I'm rigging up some of those goofy short foam element Edelbrock air cleaners under the stock chrome dome. I think you may be able to mill a bit off the stage V's carb mounting area to bring everything down a bit as well.

Okay here we go:

Stage V carb center to center 8.5"
Original center to center 6 5/8"

Stage V with 1850 Holley end to end 17 3/8"
Stock ramcharger filter end to end inside 17 1/4"

Stock hemi AFB bottom to air horn 4"
Holley 1850 bottom to air horn 3 1/4"

Stage V and Holley front carb bottom of manifold to air horn 8"

Stock intake and hemi AFB's front carb bottom of manifold to air horn 8 3/4"

In a nutshell the Holley's aren't going to work with the stock air filter very well as they are too long.
I would check the newstyle AFB's as they will be lower than the small top hemi ones are, you should be able to make the Ramcharger work with the new AFB's, a modified baseplate and some offset air cleaner studs.
