The 460 has a 3.85-inch stroke

The Ford 460 engine was first introduced in 1968 and has since become a popular choice for car enthusiasts due to its potential for customisation. The 460 has a 3.85-inch stroke, and its displacement can be increased by swapping out the stock crankshaft for a stroker crank with a longer stroke.

A stroker kit typically includes a crankshaft, rods, pistons, rings, and bearings. The longer stroke of a stroker crank increases the distance the piston travels, allowing for a greater displacement and more torque. For the Ford 460, stroker cranks with a 4.150-inch stroke will result in 502 cubic inches, while a 4.300-inch stroke will yield 521 cubic inches. The largest "easy" stroker option is a 4.500-inch stroke, which will result in a displacement of 545 cubic inches.

It is important to note that increasing the stroke of an engine will also increase the weight of the crankshaft, which can affect the engine's performance. Additionally, the longer stroke can also lead to more side loading and increased bore wear. As such, it is generally recommended to use a longer rod with a 4.500-inch stroke to reduce these effects.

When considering a stroker kit for the Ford 460, it is crucial to take into account the deck height of the block, which changed over the years to lower compression. The deck heights are 10.3000 inches for 1968-1970 models, 10.3100 inches for 1970-1971 models, and 10.322 inches for 1972 and later models. Knowing the deck height is essential for ordering the correct parts and avoiding piston-to-head contact.

Another factor to consider is the type of block. While a two-bolt main block is sufficient for naturally aspirated applications, an aftermarket block or a Cobra Jet block is recommended for higher crankshaft speeds, forced induction, or nitrous applications. Additionally, some Ford 429 and 460 blocks have four-bolt main caps, which provide added strength.

In conclusion, the Ford 460 with its 3.85-inch stroke has a range of customisation options through the use of stroker kits. By swapping out the stock crankshaft for a stroker crank with a longer stroke, it is possible to increase the displacement and torque of the engine. However, it is important to carefully select the appropriate parts and consider the deck height, block type, and potential performance trade-offs when modifying the engine.
