When to upgrade to LT4 kock and MSD ignition
#2
upgrade
a lot of people will upgrade to the lt4 knock mod. when they add roller rockers the extra noise from the rockers can play havoc with the lt1 knock as far as an msd 6 box when ever i would recomend a wire,coil,and plug upgrade at same time

Ditto what Mike383LT1 said. I did exactly what he described; excellent results. Installed the MSD 6AL first; great SOTP mod, and followed it w/ the LT4 Hot Cam/ kit w/ new coil (MSD Blaster), MSD 8.5 wires, NGK plugs, and LT4 KM. You should feel the difference! Good Luck!!

I had a 94z with hot cam and rockers, headers, cut out, exhaust and had 0 degrees of knock according to my auto x-ray scanner. I also could tell no difference with the coil and 6a. Could be my but meter is broke though
good luck
