I have a 94 with a 302 and a/c. I was wanting to delete the smog pump beings I have all new exhaust, I was wondering if anyone new what size belt I would need to bypass it?

 

Put a piece of rope around it and measure it.

 

Or go to a junkyard and look for a 96 (OBDII) 302/351. They have a factory idler pulley where the smog pump used to be on the older models.

 

Thats a good idea dixie460. I bought the smog delete bracket and was going to use the same size pulley as used on the aircon delete option so the belt should be close to standard size.
what has anyone else done about blocking the pipe from the smog system that goes into the exhaust?
