Nope!
Chevy Rod Journal = 2.100"
Ford Cleveland = 2.310"

The LS7 rods are plentiful because the folks that have these engine's want more. In the case of my engine builder, offset grinding a 351C crank from a 3.700" throw, the chevy journal size is use because it is smaller, in other words the rod journal are turned down to the chevy size eliptically to the out side.
So when you are selecting your parts the LS7 rod is an option.
You could use this rod on a standard crank but the rod journal would have to be cut to the smaller chevy size, you would have to find pistons and then get it all balanced to each other. Its doable but is normally done in conjuction with a stroker engine.

If you need some advice my engine guy is; Keith at Rancho Performance Machine, 28073 Diaz Rd, suite I, Temecula Ca 92590, 951-676-9292.

Pic is of the pistons I used, Keith machined the domes to lower compression to 10.7:1
