I would call Wilson to get there advice. Ray Barton told me blending an adpter to the intake was worth power. But now you have shortened the plenum, plus with the short adapter. See what the experts say, it's their adp. What fuel are running? The hard coat will be removed from adp.  Don

Do you need that 1/2"? You could try a cheap 2" adpt. Or get another swap meet man and cut and weld the adp. to it and then blend it. Your way may be best, you dont want to drastic of a change from adp to man. You can see how the Wilson adp is more sloped than a Moroso 2". Call Wilson, I know they are busy now, but they are customer friendly.  954-771-6216 Let us know what you do& results please Don

had 1" taken off my indy sb intake so I can get everything under the hood. I have a 1 1/2" wilsons 4150-4500 adaptor that needs blending to intake. looks like intake carb pad is about 1/8" bigger than the opening in the bottom of the adaptor. not sure if wilsons has some science in the degree of taper in the adaptor. should I blend the adaptor flush with the intake or just leave it alone and run it?
Being that the adapter is larger than the manifold
I wouldnt really worry

on small blocks between 600-700hp dominators on adaptors seem to work better than bolting the dom directly to the intake.
Same is true on most big blocks...But I cannot change my hood this year, and I was not going to pony up for a new intake when I already port matched this one...took me a week. So, pulling the undersized 950 off and going to a 1100cfm SV1, the answer was obvious, make it work. Bet mine still makes +20hp more than it did with the 950...Ad besides, since its matched to the tapered spacer, if there is room, I can still put that on...

Me personally, I have NEVER seen this to be the case on a small or a big block. Now, it might make more power with the adapter, BUT, it is not because of the adapter, it is because the adapter adds plenum volume in most cases. You could accomplish the same thing by having your manifold fixed for a Dominator and then just using a nice spacer under the carb. Work just as well AND gain a little more hood clearance, as a 1" spacer is probably all you would need.
