Is there an easy way to determine if a MM is wideblock?

[AustinTSI]

I'm looking for a Mighty Max and I want to be certain that it has a 64 wideblock.

Is there an easy way to tell by just asking someone on the phone? Like a certain digit on the VIN number.

Thanks.

If it's a 4G64 and in a Pickup, it's a wideblock.
If it's in a Expo Van, it's a narrowblock.

Or if is a dodge d-50 then it is a narrow.
