Thus, hemi-heads, because of their lack of squish, are more sensitive to fuel ; a given compression ratio will require a higher octane rating to avoid pre- in a hemi engine than in some conventional engine designs such as the wedge and bathtub. We also upgraded the pushrods during the cam swap. Bore was the same as the 291 at 3. Since the combustion chamber is a partial hemisphere, a flat-topped piston would yield too low a unless a very long stroke is used, so to attain desired compression ratio the piston crown is domed to protrude into the head at top dead center, resulting in a combustion chamber in the shape of the thick peel of half an orange.

The big, heavy Ram now stops faster than a Ford Police Interceptor, and in roughly the same distance as an Intrepid. The stock cast-iron manifolds were run with collector extensions, as the length of extension had a decided effect on power production lower in the rev range. The engines based on the old Chrysler design predominate Top Fuel and classes due to plentiful parts, large amount of research and development, as well as decades of experience with the problems of the engine's design. Getting into the bed is easier than in some other trucks, thanks to a step in the bumper. Due to reliability problems with the primitive onboard computer which controlled the injection system, however, 15 of the 16 300D cars built with the fuel injection option were recalled and retrofitted with carburetors.
