I use a late 80's 454 TBI adapter, which GM used for a couple years when they used TBI on the GMT400 big blocks but before they developed a new manifold design. But the 454 carb pad is a bit different shape and I had trouble making sure the sides were properly sealed.
Ahh, so late MarkIV engines would have used that adapter? 88-90ish?
