Okay, I've spent the last like 3 hours searching every possible combination of numbers and words to find the crank casting number I have, the closest number to what I have is a 14088526 which is a cast iron 86-up one peice rear seal crank, which from what I can tell just by looking at it is what I have, but my casting number is 14088528, and no I'm not reading it wrong. I've came across one site that mentioned that it might be a cast steel crank, can anyone help me out with this?
Thank you,
Dan

Are you sure it isn't 14088523
-
I don't think so, I looked it over real good again just to make sure of it, It is definately 14088528, but since I've seen a few other people on the net asking about this, why doesn't anyone have any info on it, just seems weird.
-
would you mind taking a pic of the casting # for us?
-
here are a few, their the best I could get with the lighting and what not:

I just built a 2 bolt main 350
It's still on the stand, oil pan side up
I too have the same crank casting number
1408852(?)
Even in the photos you posted the last number looks like an "8"
Looking at mine it hard to tell if the last numbers is an 8 or a 6.
but if you compare the two 8's in the middle,
you can tell they are different than the last number
the 8's in the middle have a small circle on top
and a big circle on the bottom of the 8
The last number looks as if both circles (?) are the same size, leading me to believe this is a "6", not an 8.
it's a nodular iron crank

the crank has additional numbers and markings on it
I can post the ones I have
but it will have to be tomorrow....
-
yes I can definately tell it is a cast crank from the thin parting line, but I'm still certain the last number is an "8" and not a "6" but I'm thinking of changing out the crank anyway...
-
Hard to tell by your pix but I looked it up in a casting ID book I have and it says 350 cast crank one piece rear main seal
-
Mine has a circle with a * in the middle with the letters CFD after it

Blue 82 I was referring to 85mudMonsters casting #
-
vile what book is it that you have and it actually had the 528 in it? was that all it said 350 1 piece seal and cast crank?
-
Could it just be a fault in the mold, there is no indention on the left side of the last number like the other 8's in the sequence?
-
i think this might help you

I don't know but I want a nodular or forged crank so this on is gonna go away since I can't figure out what it is....
-
Well which do you want Nodular Iron or Forged Steel? ???
I think you are misunderstanding what the construction of these cranks are. For the most part you have one or the other. Most stock cranks are nodular iron.
Forged isn't really necessary unless you are supercharging/turbo charging/N2O etc. Or if you'll be making some serious power....
-
I agree with Vile, you are understanding the construction. There are only 2 types.
From the pics you posted it looks like a stock nodular Iron crank, so if you are wanting nodular or steel, you already have one of those.
Post a pic of the parting line. (where the 2 halfs are joined) that runs down the lenght of the crankshaft.
-
So your saying a cast iron crank is a nodular crank. I always thought there was a differance between the two. Well, In that case I'll just keep the one I've got I'm only trying to make 400ft/lbs of torque.
