I was just wondering if a choke is nessicary to have on a street car and what are the effects of not having one?

Also, holley says "For street cars the vacuum secondary carburetor works best on midweight or heavyweight cars with an automatic transmission. They are more forgiving than a Double Pumper is because they work by sensing engine load. The mechanical secondary carburetor is best on a lighter car with radical camshaft and a lower gear and manual transmission or on a car that is going to be used for racing purposes." for secondaries.
I have a heavy truck, with low gears, a 292 dur camshaft, with an automatic trans. Which one would best apply to me?
