My apologies if this is a repost. I have a '93 in which I have put a 351w with the MAC swap headers. I also have a flaming river quick ratio manual rack. The problem that I'm having is that I cannot get the steering linkage (particularly the top u-joint) to clear the header. The bottom of the u-joint hits or rubs against the collector of the header. Has anyone here run into this problem with a 351? I would guess that a 302 wouldn't have this problem due to the difference in deck height. Any suggestions welcomed...
