| − | ''<blockquote>Keep in mind that just because the OEM numbers between two carbs may be different, it doesn't mean they are different carbs. It's very possible to have two carbs, their date is 2 years apart, one is for Buick and one is for Chevy Truck, and one is for automatic, the other for stick, and the carbs are identical in every single way, even down to the jets and metering rods. It's much more common than you might think. Also, many people think they have to have a carburetor with a certain exact OEM number. This can sometimes be very very hard. Most people don't have to have this, they really only need a carburetor that crosses over the same and is identical. You realistically only need an exact OEM number if you are restoring a car back to original condition to enter into a car show."</blockquote>'' | + | ''<blockquote>Keep in mind that just because the OEM numbers between two carbs may be different, it doesn't mean they are different carbs.
