I recently bought a 71 with a 454 already installed, and was told all I had to do was wire it up, get shorter valve covers,and a paint job! Well... after looking closely, the headers hit the steering box and I have read threads on here about these problems, unfortunately they are old threads and some said you don’t need the offset mounts and some say they are definitely needed. Also I have a 4 Spd and the other threads I saw were all about auto. trans. Any help with this issue would be greatly appreciated! I am tempted to just get a small block!
