This is incorrect. The rods on a standard 302 are 5.090", but Boss 302 rods
are 5.155" long, the same as a 221/260/289/289HP. Except for improvements in
the machining under the 3/8" bolt heads (spot-faced vs. broached), Boss 302
rods are virtually identical to 289HP rods. The improvements of the Boss
design make them stronger, and thus more desirable. And although they are
hard to find, they are not as rare as 289HP rods.

This is correct for a Boss 302. To maintain deck height in this engine, Ford
reduced the compression height by moving the wrist pin to a location nearer
the top of the piston.
