AVS 2 CFM???

I have a couple of aluminum open spacers, both 2", one is a dominator to 4150 adapter.
My small block liked the 2" open, the big block didnt like the dominator, but that was cause the carb was crap.
Im gonna try the dominator adapter on a tm7, with a good carb A to B, with an m1 dominator manifold when i get my stroker together.
(My stuff all has a scoop, or no hood at all.
