Clean the side of the carburetor above the air horn or choke tower using a wire brush for degreaser. Locate the part number listed on the side of the carb. It will start with an "R" followed by either four or five numbers, and possibly a hyphen and a single digit. Look up the part number in the Holly part number reference guide. It will tell you everything you need to know about the carburetor, including the model number, CFM, and what replacement parts it uses.

Unless you modify the intake manifold with some welding an adapter plate is required to install a Weber or Holley 5200 carb on a Mazda B2200 or B2000. The adapter plate for the Weber 32/36 will work to install the Holley 5200 as well. See the attached links for additional information.
If it is a 5.7L with iron heads, I recomend the holley dual plane #300-64, this manifold will clear the four 90 angle bolts on the heads and fit perfectly. Also has a range of idle to 6000rpm. If it has aluminum heads the #300-48 will solve ur problem with the same range. There's also a High performance manifold for the iron heads with an idle to 7000 rpm part number #300-70.
