Underdrive crank pulley

[liquidh8]

Good morning. I searched around but couldn't find the answer. I have an underdrive crank pulley right now on my engine (87). I have really driven it in over 6 years, before the restoration, and it was cold when I first bought it. Question is, is an underdrive crank pulley good for an everyday driven (60+ miles) a day car?

I may end up buying a stocker just in case I have cooling and charging issues.

Thanks all.

I ran one on the 86 in my sig. and put 100k+ on it w/ no noticeable problems. That was a combination of city and h/way.

Ok, that is good to hear. I am scoping out some stockers now to have on hand just in case.
