Seeking pics of carbs (on or off cars) & service manual info showing fuel & vapor line routing for 71 382 2bbl, 72 360 & 72 400 combos.

My 71 Dodge has a Holley 6164A carb which appears to be for a 72 360 or 400 2bbl - I'm trying to figure it what it really is, what I can replace it with & where the vapor lines go.

Thanks & Happy Holidays
