need belt size for 2.93 / 4# combo

[KenCobra03]

I need a brand, number and length of a belt to fit my new combo.
2.93 upper pulley, 4 # lower pulley, new style snub idler with
1-92mm idler and 3-100 mm idlers and using stock alternator
pulley. Have this combo? thanks, Ken

i have this same combo but with a 3.2 alt pulley. i'm using a gatorback 81 incher. have about 400miles on it, so far so good.

use cobrabobs belt guide i believe you need a k080797 gates belt.

Personally i had a problem with gates belts so i use gatorback belts 4080785. Tight Fit but no problems for me.

4080797 gatorback I have one forsale $25 shipped it has about 50 miles on it.

I needed one a little shorter. I have the same combo but with a 2.80 upper

Looking at my Belt Selection Guide the closest combo is one with one 90mm idler vs. your 92mm. Shows a Gates #K080797.

You didn't mention a larger alternator pulley and you will want one with that 4# lower pulley. If you add the 3.2" alternator pulley, you will need an 805 or 810 belt.

I am looking to keep the stock alternator pulley with my mods. One
buddy has the same set up but with Stage 4 Ported Eaton and he
has no problems with the stock pulley on. He runs Gates K080785.

It seems to be hit and miss, with the majority having troubles when running a 4# lower on the stock alternator pulley. That 785 has got to be pretty tight with an aux idler on there.

I'm hoping to check out my friends pulley set up before I
go get my Cobra worked on.
