Can a cast crank block be swapped to use a steel crank ? With out to much trouble ? I know balancer an flywheel are different , but are there any other issues , I made this swap in a 340 with great results but never a 440

I think I was cast when I was born!!Yes, but no way would I do it if I already had a cast crank. They can withstand 500 HP in as is condition. With good balance work and good parts and assembly, they can withstand around 600. They are stronger than given credit for.
I agree with Rusty. Never had a problem with a cast crank at about 500 hp. I've had several people demand they need a steel crank for a 400 to 450hp build. Just plain wasted money. I personally wouldn't be scared to go 550 if magnafluxed.
Thanks , I will check thatThe eight bolt industrial cranks are longer on the rear flange by about an inch and reverse rotation, you need to compare your eight bolt crank to your six bolt crank for differences.

You beat me to it.Hemi crankshaft according to this article. Radius fillets may require narrow bearings.

I'm wondering if that's a date or if that indicates a 4.25 inch stroke with std size main and rod bearings. But unless your planning on huge power, I would probably stay with the cast steel six bolt crank and save this one for your all out build.
well I have a steel crank that is an 8 bolt flange an has the pilot hole already for the 4 speed that I have , the cast crank does not have hole drilled for 4 speed , which leads me to my dilemma of the swap , my 440 was rebuilt from a motor home with low mileage , cam was replaced with comp cam , unsure of size but is mild from what I was told , the heads are done but are 4006452 but have access to better heads , and new rings on std pistons and new std bearings on the crank ,,,the 440 will be for street driving
