Do you HAVE to run a straight bore 4 bbl? For nostalgic reasons or that you need a specific application? If not, I'd pass on that carb. It's not something to write home about. AFB's are fine, and Carter does ok, but for parts/tuneability, a Holley is the way to go IMO.
This one is ancient, and will need going through top to bottom. Never researched it, but not sure about parts availability.
If you're ok with a spreadbore on the street, go rochester Q-jet. Can't beat it when set up right and tons of parts still out there.
Carbs are like ice cream cones. Many different flavors can sit on top. Pick the one you like best.
