Wassup yall. Just pondering what you have to do to modify a d- series manifold to fit a b-series engine (ls b18b).

Im not sure if this is an every day thing, but I have seen it done before, and im am not sure if its the "right" thing to do. Any enlightenment on to this question would be greatly appreciated.

 

i'd assume you'd match them up, mark the differences, and remove material where appropriate / drill holes / enlarge / elongate blah blah blah. It's not rocketry, but i'd assume it's a big PITA.
