In 1968 the 383 became the base engine in the Road Runner package (and Super Bee). It used an AVS carb, which is available now from Edelbrock. Although produced with a cast iron intake manifold, use the aluminum manifold (P4529117), which looks almost the same once it is painted an engine color.
The Holley carbs used on 1970–1971 engines also fit. There is also a 6-barrel intake (P4529055), which uses the 440-6 carbs, linkage, air cleaner, etc. Although not an actual production package, it is still a very nice performer. The heads, valves and cam are the same as the A134
