DANGINA -- You've stated "My turning radius from lock to lock is about 1.8 turns"... and that's with the longer Fast Ratio pitman arm (and the longer idler arm, I presume, as well). At about 1.8 turns lock-to-lock, that is very, very fast!!!... something I'd love to have for the quickest pylon manuevering! (With my T/A box and longer idler arm as well, I also run a smaller stering wheel.... 11.5" diameter... helps for quicker steering action!... and, of course, a Saginaw ps pump... never run a Federal ps pump!!!).
Question: At that ratio/setup, are the inside of the front tires hitting the frame rail (typically the rear inside of the tire)?
Are you running a BB or SB? I ask because most long arm setups interfere with tubular BB headers (unless some denting is done for clearance, as required).
T/Anks ahead!!
