It's original off a 59 Vette. The primaries and secondaries are the same size so I'm thinking it's the smallest version? The reason I ask is I was trying to build an engine for the Vette that looked completely original and stock but it'll be a hopped up 400ci. 10:1 compression, ported 2.02 041X heads, 230ish cam @ .050. The 400 will probably make peak power about 5500rpm so if the carb can even get close to that I'd be happy. But if it's going to stall out at 4500rpm that's probably not going to be worth trying out.
I just finished a full rebuild lastnight
And here's a pic of the primaries and secondaries if that helps determine which carb it is
