Thanks for the replies. I posted this query to another site and got some interesting info back.
So armed with this new info I took a second look at my motor. Here is what I found.
On the block next to the starter is CON 2 A 78
In the center of the block behind the fuel pump is 377129.
Now I went to inliners casting#'s and looked up this info and it tell me that it is a 73- 84 292.
Ok great. Now here comes the confusing parts, yes parts.
1: The 78 292 had an integral head\intake manifold. Mine does not. So what you say someone could have changed the head. Well that is a possibility. Brings me to another question. What head is on that motor and where do I find the casting marks\numbers to ID it.
2: "To tell the difference between the LD (low deck 230 or 250) and the TD (tall deck 292) check the motor mount and distributor location. TD from the front is oil filter - motor mount - distributor, LD is oil filter - distributor - motor mount."
My configuration is oil filter - distributor - motor mount. This brings me back to the F0130TUH number. According to one of the truck sites (can't remember what one I have broused so many) the TUH suffix states that it is an 81 250 fitted in a C-10, K-10, C-20. I have a 78 G-20. That in it self doesn't mean much as most of these parts are interchangeable, It just adds to my utter CONFUSION.
Short or tall side covers? If I had to guess I would say tall (8 or 9 inches) as I don't know what you mean by Short or tall side covers?
Fuel pump in center of engine or motor mount? (Fuel pump in center is 292)
Fuel pump is in center of engine.
HELP PLEASE
