What size pulley Should i order?

[The Ripper973]

Hey guys just trying to get an idea what kind of pulley i should look at running. Iv tried looking around but haven't found any solid information with something similar to what i run. Here is the setup i will be running.
*Headers With a ZZP Catback
*Ported Lower manifold with a SSIC (GEN 3)
*K&N intake
*E85 With either Deka 60# or 80# Injectors (Contemplating a fuel pump upgrade.)
*Custom Tune Will be done
*104 Plugs, 180 Thermostat
*Yella Terra 1.8s with LS6 springs

Right now im running without rockers and E85 on a 3.2 @ 17* of timing on 91. Im thinking about maybe a 3.0 on the same timing or possibly even a 2.9. Just want some opinions before i go any further or if a 3.0 or a 2.9 is way too small for what im going to be running. Thanks All!

If there is no kr, go to a 2.8. You need a machined snout to go smaller than that.

Depends on the pulley system. Some can go smaller than a 2.8 without machining.

You are most likely going to need a pump and rewire to go smaller than a 3.0.
