Perfect fit, for spread bore to TBI doesn't raise throttle body too high and seal well.

Bought this to swap my TBI onto an Edelbrock intake in my Vortec motor swap into my 88 GMC C1500. I got it all together and got the truck running and it was whistling really loud at the throttle body. It seemed as if the front bolt was kind of loose so I snugged it up. Not overtightened, just snugged it up. Well, then I had a MASSIVE vacuum leak and I couldn't start the truck any more or the revs would go through the roof. I took it loose and realized that the thickness of the adapter is tiny, like 1/4" tiny, which means the factory bolts for the throttle body are too long. This caused them to go through the adapter and make contact with the intake manifold. It put a dimple in the intake and bent the adapter so it is completely useless.DO NOT BUY, THIS IS JUNK. Spend the money on a Holley instead.
