Chrysler increased the bore size of the 383 to create the 400. Its bore of was the largest used in any production Chrysler V8 at the date of its introduction. All parts except for the pistons were interchangeable between the 383 and 400. Crankshafts were of cast iron composition. Three versions of this engine were available: a two-barrel/single exhaust version producing at 4,400 rpm with of torque at 2,400 rpm, a four-barrel/single exhaust version producing at 4,400 rpm, and a high performance four-barrel/dual exhaust version rated at at 4,800 rpm, of torque at 3,200 rpm. All three versions used the same 8.2:1 compression ratio. The 400 was used in car, truck, and motorhome chassis. Horsepower and torque ratings gradually declined through the years due to the addition of more federally mandated emissions controls, until all Chrysler passenger vehicle big-block production ceased in 1978. For its last year of production, it only produced (although a heavy-duty version was also available). Due to its large factory bore size, short (compared to RB engines) deck height, and bottom end strength that is greater than any other production B or RB engine due to extra material added around the main bearing caps, 400 B engine blocks have become a popular choice for high-performance engine build ups. RB engines The RB engines, produced from 1959 to 1979, are raised-block (taller) versions of the B engines. All RB engines have a stroke, with the bore being the defining factor in engine size. All RB wedge engines share a deck height of , and were fitted with long connecting rods, resulting in a 1.80:1 rod ratio. Bore center distance is . All RBs are oversquare. 383 Not to be confused with the 383 B engine, the 383 RB had a bore combined with the long stroke of , for a displacement of . It was only available in 1959 and 1960 on the US-built Chrysler Windsors and Saratogas; one of Trenton Engine's lines had been converted to the new RB engine (to make the 413), and demand for the 383 B
