Randy-

There are three quick checks to tell which V8 engine you have. IH engines 
are larger than their counterparts in that a 5 liter (304)  IH engine weighs 
200+ lbs more than a ford, chevy, mopar, amc, or other common American made 
V8. The same thing is true of a 5.6 (345) compared to a 350 chevy or 351 
ford, etc.

The 73 pickups and travelalls sometimes had AMC 401 V8 engines. This was due 
to a shortage of 392 engines. These are "small block" engines, nowhere near 
as big as a small IH V8 engine. If this is the case, the valve covers will 
not have INTERNATIONAL stamped into them in cursive.

If you have an IH engine, it's most likely a 304 or 345. There are two easy 
ways to identify these engines.

On the back of the block, there are two pointed protrusions. If the distance 
between them is 7 inches, you have a 304. If they are 8 inches apart, you 
have a 345. If you find it's a 304 by this method, you're done.

I have bought two 392 engines with 2 barrel carbs on them, but neither came 
that way from the factory. A 345 manifold and 392 manifold are 
interchangeable, so it "could" be you have a 392. If so, the next check will 
tell you:

The other method is the "engine ID pad" located above the fuel pump, top of 
the block, right side, near where the head and block meet, below the number 
2 exhaust port.

A link to the ID methods on www.binderbulletin.org/ (bookmark this, you will 
need it) is as follows:
