Re: 1959 Viking 40 6 speed manual
Actually alot of guys switch to the ZF in the horse power wars . They are supposed to take a good amount of abuse with a smoother shift. I never liked the ZF 6spd much since it is such a tight pattern I would miss the upshift. I have gotten way to used to the truck feeling shifter gates. The ZFs probably became popular from all the 6.0 Ford to cummins swaps.
