I have a Victor Jr. intake with a 3/8 carb spacer and a Mighty Demon carb and stock LT1 air cleaner on mine. All this under the LT 1 hood. Not much clearance maybe 3/8 of an inch but it all fits. I doubt this would fit under the stock Vette hood.

The LT-1 (or BB) hood provides 3/8" more hood clearance with a 14" round air cleaner. If you use a triangular air cleaner there is slightly more additional height with the LT-1 hood.
This was determined by swapping hoods on a 350/350 specifically to see the difference. I was amazed the difference is so small.
I run a small block, Victor Jr. with the carb pad milled .25", Holley 108-70 (.417" tall w/gasket), the standard LT-1 drop base air cleaner, and have 3/8" hood clearance to the standard hood.
