The 1850 is Holley's cheapest vacuum secondary carb. I guess it could be said that there is not a performance bone in its body. Single feed with transfer tubes, side hung bowls, drilled metering blocks, etc. However, they can be made to work well on a street driven car and they fit properly on the manifold without significant linkage fabrication. With the suggestions above, yours should work just fine on the street.
