I would not believe all that 37 hp gain, maybe if you already have heads and cam and are changing from the stock intake but not just bolting it on.
I would think you would pick up about 10 to 15 hp but the heads would be the first on the list to change and would make the biggest difference.
If you want that heavy vert to move I would definitely be looking for some heads.
They have a set of gt40-x heads on the corral for $650 and you can find deals like that and better all the time.
