Does anyone have a TB spacer? I am very skeptical about these products, however I will say that in a very different application on my 71 351C engine I did pick up some seat of the pants pull down low and mid range power. But that was a carburetor and a much larger engine. So an and all opinions and reviews (I hope more reviews and maybe a Dyno sheet?) are welcome. This would be a great power for the dollar mod if it does indeed make any.
