honestly, it’s probably not worth it. IF you do need help though… lmk, I can run all kind of flow tests here at work with a crude mock up of a manifold [3d model]
If anything, I’d go with some turbo specific cams/full exhaust (if you dont have it already) and maybe some mild head work.
or just say fuck it and pick up the RWD, 302 v8 conversion… that thing will HAUL some ass lol
