5.0 Belt Issues

[Jarrett howell]

I have a 89 vert 5.0 and i need some info on belt size. It has stock pulleys still has ac and no smog pump. I used the 84.5 belt and it is very very tight and when the car is running it has a intermittent squealing sound like the tensioner pulley has too much strain. Any thoughts?

If it's too tight, get a larger belt. Does the tensioner fall into the range indicated on the face?
