I have a super sniper fed 512rb. Currently it has a 1 inch open spacer into a trickflow single plane intake. I want to add a merge spacer from Wilson. I know that there is no magic formula that would work on all cases. That being said, if you were going to buy just one merge spacer for my setup, would you buy a 1 inch, 1.5 inch or 2 inch spacer. I have a large hood scoop so clearance is not an issue?.

If you’re only buying one........I’d just go with Wilson’s recommendation.
Now that makes total sense. Why didn'tI think of that. I will contact them directly
 
This sounds like an episode of “Engine Masters.” Lol!
They did a whole thing on those spacers.
 
I have not heard back from Wilson yet, but research on their site explains it pretty well. The taller spacers give more top end but compromise bottom end.

Picking the Perfect Spacer | Wilson Manifolds Blog
I wouldn't assume that the motor wants a spacer. Cheapest thing you could do is try it with no spacer. Especially if it is a mostly a street driven car. I have seen on the dyno where no spacer picks up the bottom end with little or no loss on the top end. I have also seen good gains mid and top with the right spacer with little or no loss to the bottom end. Don't count out the no spacer option unless you have already tried it. Keep in mind changing spacers can also change the air fuel ratio or the jet the motor wants. Generally but not always no spacer = less jet and spacer = more jet. It might be tough to sort out by seat of the pants.

Every engine is different, but you may want to try and borrow one of those spacers before shelling out for one. I'm sure those are effective on some engines, but mine didn't care if it was on there or not....on an engine dyno.
