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

Mike very nice. Do you have any before/after results?
OP is looking to gain hood clearance.

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.

On the Mopar's big blocks, the 2" adapter for a Dominator to a 4150 has been proven to add 10-15hp...Yes it adds plenum, but in back to back tests, many on here have seen it. All the way back to when Team G was the intake to have on a nice stroker 440 Wedge engine...On the small blocks I have not seen this, but on a big inch small block, more plenum is certainly needed on most of today's intakes.
But just the same, some of us already had a 4150 intake and now need a Dominator, so we make it work.
I pulled the intake off the Hemi today and made it all fit the SV1, with and without the tapered spacer...I did not do a before and after picture, but there was a lot of meat that had to come out and its cold enough out today the die grinder froze solid in my hands...Air compressor must have had a little condinsation in it.

nice work. looks real nice with the sv1.
With a little time and effort and some hand tools, it can still be done...I already ported the Wedge intake to fit, but took it down to the shop for some heavy milling on the efi bosses to remove them. Figured, if I am going to clean it up, might as well go the whole way this time...
The SV1 was purchased for the big wedge, but I also want to try it on the Hemi...The Hemi was also running yesterday with a 4150 on, while the wedge is still a couple of weeks away. Lots of winter fun...At least its not -2° like last week...
