Re: Exhaust Question
Your '77 might not need a catalyst. In '78 the V8s had a converter, but the sixes did not, although they did require unleaded. In '79 I think they all had catalysts.
If your header outlets are aimed so that they have to be routed over the frame rails and out the fenderwell, you might be stuck. In that case your best bet would be to tuck some small mufflers up between the floor and the outside of the frame rail, and turn the exhaust down and out in front of the rear wheels. I have a couple of friends with that exhaust setup and it works pretty well, although it always seems to be in danger of getting dragged off.
I might have been born at night, but it wasn't LAST night.
