How do I tell if a crank is a forged 292 out of a truck? Have one that is supposed to be one but not sure how to ID it. Also any idea of what a turnable one is worth? I have someone localy looking for one and no idea what one is worth.

The forged crank has no counterweights in the center. You can also id it with the number or flange. http://www.ford-y-block.com/crankshaftid.htm

A cast crankshaft will have a very thin straight casting lines where it came out of the molds, whereas the forged crankshaft will have a very thick uneven line where the forging metal bulged at the parting lines from the forging process. Joe-JDC

Thanks, That helps a lot. Any idea what the going rate for one is? Not looking to get rich off it. Just looking for a fair asking price.

Yours is a cast crank. For your use, it is completely adequate.

Do you see the crankshaft throw just in front of the #2 Main? There is a thin parting line in the picture visible. Like John said, it is a cast crankshaft. Joe-JDC

Here are some pics of the various Y crankshafts. Observe that the cast crankshafts have eight counterweights each while the steel crankshaft only has six. In the following picture and from top to bottom: 292 – cast 312 – cast 292 – steel
The crankshafts are also identifiable by examining the front throws of each.
272/292 cast
312 cast
292 steel

Thank you for the images, and which one is more desirable?

What is the intended use? The cast crankshafts are plenty strong for upwards of 500 hp with lightweight forged pistons and lightweight rods. Some of the stroked 312 crankshafts are in engines making ~550-570hp. Unless you plan on installing a blower or going endurance racing, the cast should work just fine. Joe-JDC

Thanks Joe, my engine is not the final power it will have, but it sure won't be done at those 500hp
