Did you do any extensive testing with either combo? I used one on a twin turbo 468BBC at 900 ish hp and had two cylinders we couldn’t bring the AFR down in. Switched to a CSU carb hat and the problems disappeared.

Only basic mph, plug readings and O2 in the Downpipe. Was going 136-139 mph at 3400 with a basic 440 edelbrock heads. Usually ran it pretty fat so might’ve covered up some issues, but never saw a plug that was alarming. I have heard some say that they start having issues above 800
