Wiki:
The 413 RB had a 4.1875 inches (106.36 mm) bore and was used from 1959 to 1965 in cars. During that period, it powered almost all Chrysler New Yorker and Imperial models, and was also available on the lesser Chryslers, Dodge Polara, Dodge Monaco, and Plymouth Fury as an alternative to the B-block 383 and/or the 318.

In the 1959 Chrysler 300E the 413 wedge was fitted with inline dual 4 barrel carburetors; it was factory rated as producing 380 bhp (283 kW) at 5000 rpm and 450 ft·lbf (610 N·m) at 3600 rpm. In 1960, a long-tube ram induction system was made standard on the Chrysler 300, it continued as standard on the 1961 300-G, it remained on the option sheets for Chrysler 300s through 1964. In 1962 a special version known as the "Max Wedge" was made available for drag racing and street use, this version produced 420 bhp (313 kW) at 5000 rpm. The 413 remained in use in medium and heavy duty trucks until 1973.
