Looking for information on 411 ECU

I am planning a coil per celender update to my SBC.

Has anyone used something like this for their manifold?

Well, I guess I asked that way wrong. How does this fit under the hood and does it work well with the LS1 style ECU?

Depends on which intake you use, which throttle body or if you use an elbow. The 411 works fine with anything as long as the sensors are compatible. Its easier to use an elbow with ls1 style throttle body and sensors
