The 460 Ford engine block is designed for a maximum stroke of 4.38 inches. In order to fit a 4.75 stroke crankshaft, the engine block will need to be clearanced for the longer stroke. This can be done by either offset grinding the main bearing journals or by using longer connecting rods. Additionally, the oil pump pickup tube will need to be lengthened to accommodate the increased stroke.
It is also important to note that using a 4.75 stroke crankshaft in a 460 Ford engine block will increase the engine's displacement to approximately 514 cubic inches. This will require the use of larger pistons and a correspondingly larger carburetor or fuel injection system. Additionally, the camshaft timing will need to be adjusted to account for the increased stroke.
Using a 4.75 stroke crankshaft in a 460 Ford engine block can be a great way to increase the engine's displacement and power output. However, it is important to be aware of the necessary modifications that will need to be made to the engine block and other components in order to ensure a successful installation.
