Whats better Manual steering or Power?
It would seem that the major advantage of manual over power in a strip car would be less weight on the front end. Horsepower consumption; 3 hp seems more reasonable than 11, lacking any data, should only be an issue mainly for those restricted by narrow class rules.
In addition, depending on your performance goals, V-belts don't really like 7000rpm shifts; not to mention that the combination of p/s fluid and hot headers is never good.
I do know that the choice here comes down to a matter of personal preferrence, just like the colors we paint our cars, but for me, at least in an A body, I'll take manual.
