To buy a 4bbl/intake/cam/headers/all of the supporting mods you have to do to the slant might be as much as a budget v8 swap unless you find these parts used and for a good deal but even then it will not be cheap.
Xs2 some of that slant six 4 bbl. stuff is way more than a v8 build which is why I suggest a super six setup which is a 2 bbl. and a factory part so its not all that expensive and makes a huge difference.
