Helo From Tucson

[Chewvaca]

there, i'm an 18 year old from tucson, and my dad owns what seems to be a 1987 short-bed chevy custom deluxe. I am not sure of the year because he bought it in Mexico and its supposed to be a 1990 there, the truck has the stock 350 but I want to make sure what year it is. it also has a 302 ford carb on it and I want to know which is a good (or the best) carb for it. Im looking into Edelbrock carbs but since i don't know the year of the engine im not sure which one to buy . Any Healp Please
