I'm running a 671 blower on my sbc and had to cut the hood. I've seen alot of blown bbc in trifives but none were ever tucked under the hood. The hood was always cut. Not saying it can't be done; I've just never seen it, Carmine.

 

My big block with just an airgap dual quad and moon oval air cleaner my just clear the hood if at all. Williams 3/4" forward mounts as well.

 

this was in my 56 pickup

it will give you an idea on location and height,

 

Anybody have any idea who's 55 or 56 chevy this is? It popped up on the Car Craft facebook page and i can't any more info. I'm working on a similiar set up with side draft webers for my 56. My big block is lowered to about the same height as this one.
Any info would be great, I just want to find more photos.

 

Have a magna supercharger on my Corvette. Sits pretty low. Might check their website for dimensions. I would think procharger would have the pulleys to add their unit to just about any application. Did you call them? That is a lot cheaper that a supercharger. I think mine ran $6-7000 for the Corvette. It is inner cooled with electric water pump, radiator, etc.
Attached is a pic.

I dont know much a SC's but i saw this side supercharger under the bonnet of a 57 and thought it looked pretty neat, could be worht some more investigation?

 

The driver works the gas and the passenger works the brakes on this one!
:rofl:

 

Do any of you run a smaller roots-type blower on a BBC that tucks completely under the hood of your '55/'56? If you've gotten that far, how about room for PS and A/C?

There are several guys here on Trifive that have small blocks and the small blowers under the hood.
The 55/56 has more room under the hood than a 57.
It will be close and probably depend on the air cleaner you run.
My 57 BB with small blower will not fit under the hood.
The carburetor is above the hood about one inch without air cleaner.
Also with any blower you need to think about the size of the air cleaner.

Check out Alston chassisworks, they got gear drive setup I think bolts directly to the front of the engine.
