I wonder if Rams Horn Iron Corvette manifolds would clear the steering box? Only way to know would be if someone has tried it. The end exhaust ports are routed up in a semicircle to the center where they come down and meet the two middle exhaust ports. The only concern I'd have is if there's room next to the steering box at the middle exhaust ports.
Is there? I know it's only a swag, but by eyeballing it, would you say there would be room for ramshorn manifolds?
