Corvette LT-1 Serpentine Belt Question

I can't help your problem except my 92 had the double sided belt. Was there more than one belt for that year?? You will have a grooved idler for the 2 sided.

I have a 1993 Corvette LT-1 crate motor that I'm running in a non-Corvette application. I am using 1992 Corvette accessories and have encountered a problem getting the correct serpentine belt for this combination. If I use the double sided late 1993 belt it fits extremely tight and makes the tensioner practically useless. The single sided 1992 belt is too loose and the tensioner is useless. What's wrong here? Is there a difference in 92/93 harmonic balancer diameters? P/S, A/C, diameters? Or, maybe the idler and tensioner?

Any suggestions are appreciated as my local Chevrolet dealer (I live in a small town) is practically useless in trying to solve this problem!

Thanks, Jim

I know they changed the tensioner in mid production year of 1993..ie there is a different tensioner for early 93's and late 93's
so if you have a late 93 engine and trying to use 1992 acessories then that probably wont work...it seems they changed many things in the middle of 1993 production.
if there is anyway you can get accessories from a late 93 or newer then that will probably solve your problem
