Welcome here. You would need a BB bellhousing & I'm sure the related BB clutch parts (flywheel/disc/hat/fork etc) . BB pump housings are available to match your current radiator lower nipple side position IF it has enough capacity (I'd want a 3 row) & is in good enough shape (not partially clogged). Wiring can be extended easily (always keep the same color including color with tracer as OE). Headers make the most power but have issues, not sure what brand to recommend. iirc the K member is the same you just use BB mtr mts (others will clareify).
