Edelbrock carb - period correct?

[1968_K20_4x4]

Hey guys,

I have a 1972 Chevy K20 that was not running right when I bough it last year, so I bought a new Edelbrock carb to get it going. The truck is fairly original, and I want to keep it mostly original and period correct to the early 70s. So my question is, were Edelbrock carbs around and being used on our trucks at that time? Or did they not come out until later, like in the 80s? Thanks!
