Hi.

Will my Edelbrock 4 barrel carb (1405) fit this intake? Or will i need an adaptor? 

Do i need a Carb Spacer?

It fits.  As long as the throttle blades don't bind, a spacer (or other modifications) is not necessary.  But a spacer usually does help with low end power and insulating the carb.  If you have the  room and money, use a spacer.

I just did this exact thing (same exact manifold and carburetor combination) a couple of months ago: The secondaries are a bit large for the manifold holes, and will bind/not work.  I used a 1/2" bakelite spacer that I slightly modified by "funneling"/tapering  (using a half-round file & smoothing with emery cloth) the secondary holes (bigger on carb side) to match carb secondary "holes", accommodate the secondary throttle plates, and match the manifold "holes".  Works just fine.
