V-8 engines were produced by the Daimler Company in displacements of 2.5 L (153 cu in) (1959-1968) and 4.5 L (275 cu in) (1959-1968). Designed for Daimler by Edward Turner, they were initially used in the SP250 sports car and the Majestic Major saloon respectively; ultimately, the 2.5 L was mostly used in the Daimler 2.5 V8 (later named V8-250) saloon made with Jaguar Mark 2 unit bodies from ...

[8] Combustion chamber design was most important in these new heads: LA engine cylinder heads were given a full-relief open-chamber design, but the Magnum was engineered with a double-quench closed-chamber type.
Design features of the B and RB engines include 17 capscrews per cylinder head, a cylinder block that extends 3 in (76.2 mm) below the crankshaft centerline, an intake manifold not exposed to crankcase oil on the underside, stamped-steel shaft-mounted rocker arms (race versions used forged steel rockers), and a front-mounted external oil pump driven by the camshaft.
Chief differences between this version and the A588 include a cast aluminum SOHC cylinder head that more easily passes exhaust gases than the base engine, a camshaft that is optimized for higher engine speeds, a factory welded exhaust short-tube header instead of a cast exhaust manifold, and a two-piece intake manifold. This manifold features ...
Head restraints were optional equipment until January 1, 1969, when their installation became mandatory under federal law. The 6-cylinder models received a carburetor anti-ice system borrowed from Canadian-market Chrysler 6-cylinder engines, [30] and the drum brake automatic adjusters were revised for more consistent operation.
