Help, with a friends 67 Cuda 340 issue

When I read that he is still running points I thought how about changing the condenser? A good electronic ignition would eliminate a lot of problems there. Also a 600 cfm carb with a Torker intake? That just seems like a mismatch anyway, even if it has nothing to do with this particular problem. A good dual-plane intake and a bit larger carb would help a lot with overall street performance.
