ok so im posting this to see if anybody knows the belt number for the underdrive pulleys for a 92 camaro
i just got the alt/crank pulley
the belt is just two big, only thing spinning is the crank!!

 

I'm not sure, but you could find out by running a sewing tape measure around the pulleys and seeing how long it is. Then just go to the parts store and find a belt that most closely matches your measurement.

 

hmm i just went up there and gave em my old one to look uop in the comp and told them i needed one that was a inch shorter then that and he was like so your bypassin the ac, i was like no i just added underdrive pulleys and yea it works fine!

still cant take on a 3.8 fbody but im gettin there!

went from them passing me at the top of first and pulling me hard to them pullin me at the top of second and me staying on there bumper!
