New 670CFM Throttle Body won\'t work with TB spacer, what to do??? I just bought a Holley 670CFM TB. I have a TB spacer on my truck. The flaps on the new TB are too big and won't open b/c the holes in the spacer are too small. What should I do? It also won't work when I put it right on the manifold for the same reason. Any ideas?
