The 282 which had a larger bore is considered the ancestor of the 4.0 stroker engine where it is common for the engine rebuilder to use an AMC 258 crankshaft in a Jeep 4.0 cylinder block-a 4.5 uses the stock AMC 258 connecting rods ( with a stock or . 020 overbore using aftermarket pistons ) while the 4.6, 4.7, and 5.0 strokers use the 258 crank but retaining the 4.0 connecting rods.
