Edelbrock offers 91 and 93 calibrations. The only difference being ignition advance at high engine loads.This is a nice kit and I love those curves and the way it brings up the torque curve in the upper rpm to make a nice level flat predictable torque curve. When I saw the Dyno I was worried you could only run 93 octane but looks like the manual says you can run 91 so thats good.
What happened? Did you install or know anyone who actually did?Have these hit the market yet?
Any sources for installs, reviews, etc?
