I have an inquiry in with Tom at 12bolt about which intake (Offenhauser or Clifford), and which carburetor, the 750 cfm Holley with his conversion kit knocking it down to 562 cfm, or a Weber 38/38. I like the idea of the 750 running on 1 barrel until the secondaries open, but I have also heard good things about the 38/38. I want to keep my stock exhaust manifold, and will be running 2.25 exhaust with glasspacks on my 292. Eventually the head will get the lump kit installed. Tom is on vacation at the moment and should be able to respond to me next week.
I am very interested in how your conversion turns out Mike.
