I think the difference is just in the pistons, but with a mild cam, 750cfm edelbrock and headers where would I be power/torque-wise?
What you have available to you is the common carbureted 460, spec'd essentially the same from 1973-1986, the primary exception being 1979-up is externally balanced and 1978-earlier is internally balanced.

With your addition of a mild cam and non-retarded double roller timing chain, 750 carb and headers, you will be barely north of a realistic 350HP. Usable street power will be quite good, and I bet the Ranchero will smoke the tires all day long.

Should you want more power than that: two factors will be keeping the power restricted, namely the 7.9:1 compression ratio and the restrictive exhaust flow on the cylinder heads. You may port the heads and install flat top pistons and be over 400HP...with the potential for much more with a cam change. Or, you may swap out the heads for early style higher comrpession heads so that compression goes up without taking the shortblock apart. These suggestions assume you are hoping for way more horsepower than 350+.
