Woo-Hoo! That 454 I bought turned out to be a 4-bolt!

I finally got the oil pan off and low and behold:

Now I'm PSYCHED!!! Off to the engine shop soon.

Why can't I be lucky like that?

You are going to have a real monster!

Congrats on the bonus discovery! How about the crank? Is it cast or forged?

 

[Paranoid]

Cast or forged??? I don't know. How can I check?

 

[69MyWay]

Look at the counterweights on the crank (the large chunks of metal inbetween the journals).

If it is cast, you will have a fairly thin ridge running along it as if you are looking at the edege of the two part mold it was cast in. If it is steel, you will have a wide (finger width) seam that runs along the counterweights. It will be as if a thick bead of weld was laid down, then ground smooth vs a more hap hazard 1/4" or less kind of pointed edged seam.

Sorry, but I can't tell one way or the other. I did get this #353038 or 039 from the crank.

Evidently, that's a cast #---I wasa hopen':crazy
