Jon,
No I'm not looking to run it at high RPM and I do not have a two barrel manifold but the hole in the intake is 1/4" bigger in diameter than my current carb and I thought that an adapter would be able to take advantage of that bigger size. Again I'm on the steep end of the learning curve with this but thought two stage would give me good low end performance and economy and a little more help on the top end when it was ocasionally needed.
