I think that a forged crank is in order at that hp level. Why didn't you just buy a full rotating kit from 440 source to start with? A stroker kit wouldn't have cost you any more than a standard 440 kit.

Yes we all would prefer the steel crank over the cast but how many have you seen let go ?
My first race engine was, still is, a cast crank stock LY rod engine. It's been to hell running 11.00's for years and then high 9's on the bottle over a 150 times. it has a sleeve, 7 TRW pistons and 1 Manley that was shaped with a grinder to match the others, ran a best of 9.69 @ 135. The engine is still going hard in my sons Aussie A body N/A running 11.2.
I would say that a cast crank will be fine up to 600hp.

I've never had a problem with a cast crank. It was the stock, cast pistons that were my undoing! This made me laugh............a lot..........

You know if you could get that thing to hook up, it would accelerate a lot faster... Crazy Aussies! (I wanna be a tire salesman in Austrailia!)

$250 for a stock forged crank that still needs machining??? Holy crap that's high! You ought to be able to find one cheaper than that!
Realistically, I think a cast may be fine for what you want to do, but I'd rather see a forged crank in a motor making that much power. You've already spent good money on a girdle, studs, etc. Get a forged crank and don't worry about it.

Should be a million of the steel 440 cranks laying around with everyone using strokers now, and cheap too. Like the guy above said, maybe $250 for a done crank. As said in the next post, RB steel cranks hold a premium to go into a B-motor budget stroker. At least $100 for a core that needs turned. $200 at a swapmeet.

Not splitting hairs, but they are both steel....its not cast iron v/s forged steel. One starts out as a forged billet the other is a poured casting.
Consider this, if you are a budget build (say <500hp) or a just for fun test and tuner, it probably doesn't matter much. If you are hitting it fairly hard, or drive the stripe with the throttle pedal, you should probably stay away from cast. No they are not both steel one is iron and the other is steel its sort of like saying brass and bronze are the same

No they are not both steel one is iron and the other is steel its sort of like saying brass and bronze are the same I dont remember the ASTM number right off , but here is a link you can refer to until I find or remember it....they ARE cast steel. Not totally relevant, but as in your comment - its like calling brass and bronze as the same. Bottom line, go forged. http://www.hotrod.com/how-to/engine/1405-how-to-tell-forged-crank-from-cast-spotters-guide/
