HELP. I JUST MOUNTED MY 350 INTO MY 50 3100 AND REALIZED THAT MY STOCK STEERING BOX WEL NOT CLEAR THE ENGIND.i KNOW SOMEONE HAS RUN INTO THIS PROBLEM AND WHAT DID YOU DO TO SOLVE IT.
Won't go into detail, but options are: Move the box, upgrade to power steering, check out headers and manifolds. A search will show this topic is well covered. I looked at your photos and with that in mind, I think power steering is your best bet.
