I need to know how many inches smaller i need to go on a belt, i also have a crank and alternator pulley. thanks

 

As far as the A/C delete, it doesn't require you to get a smaller belt. I don't know the length needed for the pullies, but they sell the belts for the pulley sets on LS1speed.com.

 

Do a search, its a common problem with people with after market pulleys,

 

Trial and error.
I have an underdrive pulley on the crank and AC delete but no alternator pulley.
Took me 4 trips to the parts store to get the right belt.

Goodyear Gatorback if you can find it, no squeals.

 

Thanks guys,.. i already have a good fitting 59" belt for the crank pulley and alt. pulley set-up. i was just wondering with this delete pulley is that gonna make me need a smaller belt, or will this one work? Well ill prolly do a search when i get home from work,... or just see what the mechanic says this afternoon when i get my car back,.. i just kinda wanted to know b4 they put the belt on and it possibly not fit.
