Never mind, found it.....
The 'B' series wedge engine was introduced in 1958 with 350 cu in (5.7 L) and 361 cu in (5.9 L) versions. The 361 would continue in production until the end of the series, albeit only for truck installation. The RB ("raised B") arrived one year after the launch of the B series engines, in 383 cu in (6.3 L) and 413 cu in (6.8 L) displacements. Unlike the previous B-engines, which had a 3 3⁄8-inch (85.7 mm) stroke, the RB engines had a 3 3⁄4-inch (95.3 mm) stroke.
