OK, whats the motive? You arent doing it for mileage, that you've made clear. I dont think its for the power either. If it were for the power, you wouldnt even consider the carb and header. For the cost of them new, you can swap in a used 302 engine/tranny combo.
Is it for the looks?
v8s always look better. They're more "balanced" looking. Carb in center, headers on each side, distributor in the center. Whereas the 4 banger is lop-sided. Intake on 1 side, exhaust on the other, distributor stickin out crooked on 1 side.
My opinion....dont do the work to the stock engine. Really not worth it. By the time you get it to a measly 150 hp....you spent enough for a 400hp v8. And IF the v8 is EFI...swap the rear end for something with better gears, like 3.73s or less, and get great mileage.
