Turbo 383 in a A-body Barracuda

5" to two 3" passenger side. I tacked it in place and pulled it out and final welded all the seams and "Dammit" the front one that goes under the oil pan moved rearward. Gotta notch it and bend it back where it was to begin with. Decided to go with what I had instead of the 4".
