ufo,
I know what you mean by "3 tube" header (single center pipe), but can you tell me what manufacturers, and fitments would fit on a 78 G-body? I mean like, if one listed for a 73-77 Lemans/GTO/Grand Prix (A-body?) 400 would fit a 78 G-body with a 400. If so: what, if any, hammer modification would the headers need?
