How to ID Crankshaft

[pontiacgp]

chevy....if you have 2 cranks side by side it's easy to tell the difference but when there is only one crank tapping it with a hammer is an easy and quick way of determining if it is cast or forged..

I dont need two cranks to tell the difference i know what i am looking at . Anyway dont know why you keep coming back with smart *ss replies just trying to give you the comin knowledge off what to look for. Maybe you should take that into consideration or just dont ask a ? if you dont want any answers.

smart *ss replies?...well maybe you don't need two cranks to tell the difference but it wasn't you who asked the question was it....must be that time of the month for you....

Chill out guys.

Both of your knowledge points checked out. I checked my old crank and it is an internally balanced forged crankshaft.

It doesn't have the cast seam and I took a hammer to it. That high pitched sound lasted and was definately not a thud.
