Optimizing a Holley 4175

Hey guys:

A few years back I snagged a nice Holley 4175 out of a junkyard van and it's been floating around looking for a home since. Well now it will go on a mild 383 in a heavy vehicle.

For those who are not familiar with them, this is a 650 cfm spreadbore Holley intended as a Quadrajet/Thermoquad replacement. In it's baseline form it's probably calibrated lean since it was sold for use on emissions-equipped vehicles. 562 jets and a dual-stage power valve.

My eyes start crossing when you get into 6.5, 8.5, 100.5 etc etc power valves, idle feed restrictions and all that because I'm simply not used to tuning Holley's. I'd like to know if there's a proven jetting/PV combo that would be a better fit on that MILD 383.

This is not a carb I want to be taking apart all the time trying different combo's. A couple times maybe, but that's it. I know some of you will say there are better Holley's to use, but the engine already has a 400 spreadbore intake on it and I'm not changing it.

Thanks!
