It's been a long time since I last visited this forum. I have a 79 Caprice with a 250 and am thinking of upgrading to a better carb. So my question is, if I buy the 1 bbl to 2 bbl adapter from Tom Langdon's website will I be able to use a holley or autolite 2 bbl carb or only the H/W carb he sells in his website? I've searched the forums, but haven't found an answer.
