slant 6 3 spd column to 4 on the floor

Hey everyone Im new to this and have a question, I have a 71' dart swinger that use to have a 225 /6 and now it will have a 340 in it. I am curious if i need to change any of the clutch linkage out, mainly wondering if my existing Z-bar will match up to the small block bellhousing. and if someone has done this swap before and other issues that i might come upon would be greatly appreciate! thanks everyone!
