383 Motor Failure. FML
For sure? I'm not to familiar with sizing cranks at all. I'm a first time Chevy anything, and this is my first V8 car. I was usually a turbo 4 kind of person 
Not only that, but when I look up parts, its asking me for the rod length?

So in other words... something along these lines:

EDIT
I think it has a one piece rear main... I think... so that crank but the 1 piece RMS version.

If the crank pulley is wobbling, then I'll guarantee the crank is snapped just behind/under the front main. That's where mine broke.
And I am honestly surprised that after your Eagle cast crank broke that you'd consider anything Eagle in the future. That would personally be my last choice.

I had a eagle cast in my engine at first. I Did some research. Never even installed the oil pan or the heads took it back to the builder and had a Callies installed. Wasnt worth the cost to let it completely destroy everything!
agreed........i spun a stock crank stock rod/(ARP BOLT) combo 7000rpm for 4 years when i had my 355.....
yuppp

The Eagle forged stuff sometimes needs machining to make dimensionally correct before installation but they don't break the way the cast ones do. YEARS ago the Eagle cast were popular and worked OK but in recent years HP numbers are easier to come by and something seems to have gone wrong QC wise with Eagle and in recent years their cast cranks have been failing pretty easily.
Eagle seems to be easily the most popular brand of cranks but only because they were cheap which built popularity and now that popularity is just self sustaining. You can buy better stuff for similar money. The Howards Tracksmart are made in America by Callies similar price to the chinese stuff.

Before I'll go hating on Eagle or any other CAST crank manufacturer there is one very important bit of info here. The crank was neutral balanced and the weight was left on the flex plate. That will.....absolutely introduce harmonics into the rotating assembly that are hard to overcome. A stock cast crank or any cast cran would have failed in that unfortunate situation.
By definition cast iron or cast steel will be brittle because of the increased carbon content. Brittle things don't like harmonics. If properly balanced a cast crank can make over 500 HP. If improperly balanced they can fail at 200 Horsepower. I'm not sure the fault was Eagle but from the original post the fault lies with the builder for not doing his job.

i have an eagle forged crank in my motor. it was built back in 04, 396, daily driven for about a year and a half. car weighs 3800 and puts out 502 rwhp, the forged stuff seems good to me
Both my Eagle 4340 cranks needed a bit of work to get them balanced, now they are within 1 gram a bit overkill but no problems from them yet.
Howards Tracksmart 4340 forged crank and 6" h-beam rods with Mahle forged ft pistons in my new build. I wouldn't bother wasting time on a cast crank for a stroker build, the extra $300-$400 you spend on the frontend (depending on whose 4340 forged crank you buy) will save you alot more money later when the cheap **** blows up or brakes and takes out everything else with it.
