I used ram's horn manifolds, center dump, on my 350 and had to move my steering box 2", in addition to grinding the outlet of the manifold a little. I also had to chop my firewall for Distributor clearance in order to keep the 4-speek tranny in exactly the same place. I hated this setup and now, having blown the 350, am back to a 235 with everything patched up and moved back to original.
