Which belt? Serpentine? JS to crank? SC to JS?
You should be able to call or walk into and parts store and get that info.

How about we give a little more info about the reason for the question.
We are working in a 89 sc engine with a 95 blower. We pulled the blower out of a car in the junk yard and we are assuming the pulley is stock. We are having two issues since installing the 95 blower. The belt is extremely tight, and is a battle trying to install it onto the blower even with the tensioner removed. The second problem we are having is the blower is getting extremely hot. Even with a FMIC we are seeing air temps into the high 140-150 deg range.
I have a 93 blower with an underdrive pulley. The belt is effortless to remove and install. I also have a FMIC, and usually my air temps are 10-15 deg over ambient temps.
Is what we are experiencing with the 95 blower normal?
Thanks for the help

Was this 95 blower serviced? Rebuilt? Is everything moving freely? If there blower is high mileage and worn out, that could attribute to the high head (i.e. bearing ceasing, ect)

Unless you are using an oversized idler pulley on the blower belt tensioner, or have an OD JS pulley the 393 belt should fit. It's also possible that someone may have redrilled the tensioner mounting holes (clocked) for making the belt fit tighter.
Reason for excessive heat could be the bypass valve being stuck in the closed position. Check the linkage to make sure it isn't stuck on the back of the blower. If vacuum hose is off the actuator it will remain closed.

The bypass works fine. When I rev the car you can see it move. Even without the tensioner pulley on the car the 392 belt won't fit over the pulley. Should I get the 393 belt? How much larger is the 94-95 pulley then 89-93?
The 94-95 pulley is actually about 3% smaller than the 89-93 pulley. If you can't find any reason for the belt not fitting, then yes try the next size longer.

David isn't the 94/95 3% larger than the 89-93??

Edited to fix error
You can put the early model pulley to OD the blower about 3 percent. Of use a 5 or 10 percent od pulley.
