I dont even have power steering in mine with the 351w It's not bad along as your not stopped, and is your stopped and layed out it's not bad to start..
lol that is probably one of the dumbest things I have ever heard.
On the subject, My mazda has P/S. and turns so effortlessly you forget your in a truck(along with many other aspects that contribute to that)
But today I put new wheels and tires on my 87 Nissan that does not have P/S. It had some crappy deep dish bullet hole 15's with 75 series tires. It turned like a SOB. So I put stock Pathfinders on it with new 205/60's. It now turns like a dream even stopped. one thing about no P/S is that it allows you to better feel the road and maintains some (natural return). With this setup I now have no reason or desire to install power steering. Previously I needed it in a bad way.
