Both engines are the same size externally. Tell your friend he's seeing things.
Look at the style of the heater hose fitting on the rear of the passenger side cylinder head. A threaded pipe plug looking thing that looks like a giant wrench fits it is pre 425. The 425 will have a right angle pressed in piece of light alloy metal fitting similar in appearance to what they make heater control valves with. 425 has single plane X looking intake manifold. 425 exhaust manifolds look a lot different than the 472/500.

If you are talking about size, as in outside dimensions, there is no difference between the 425 and the 472/500.
The site that The Ape Man listed might help.....check the casting numbers.
