      I build, modify, & tune custom Holleys so I can get you started.

      What do you have for a dist and were's the timing set and how's it curved?

      Your 4781 is a bit big for your combo and it usally takes a bit of mods to help them fit better.

      I would have suggested something a bit smaller like a modified 950



      I would suggest 78/84 with a 4.5 PV not knowing how much vacuum your engine produces?
