Yup, for the 99. I am wondering if anyone know'* the belt length for using the 3.25" pulley with no IC, and no oversized idler pulley on the H-body?

Need part # asap so I can get it to the shop tonight or tomorrow so I can have the motor and trans ready to drop in Thursday or Friday.

you could use a 715 belt then go to the oversized tensioner....although this is not the best setup because of clearance issues between the tensioner and the supercharger

Yeah, I just tried to figure it out via ZZP'* belts guide.
They don't give a belt # for anything less than the 3.4" for the H-body, so I figured it'* going to be the same drop in size as the W-body.
I am going to go with the 715 for now, and if that slips I'll just get a 710 and that'll be really snug.

I'd go with the 710 to begin with and if it slips throw on the 3.25 tensioner
