Yes, but you'll have to have the assembly re-balanced and change over to a neutral balance damper, flexplate/converter/flywheel, as the steel cranks are generally internally balaced, while the cast are external. Hence the need to change the damper/flexplate etc.Hi my question is can I put a steel crank in a late 70s 440 that came with a cast crank?
Yes, but y
Thanks. I just wanted to know because there are a few 440s with cast cranks close to me but I didn’t want to buy one if it could not fit a steel crank. Are all the steel cranks internally balanced?

Depends on how much you can get a forged one for and machine costs and what you're doing. I paid 75 bucks for my forged crank, plus 350 to have it turned .010 and rebalanced with new rods and forged pistons.I'm going to jump in here with another related question. I just bought a 440 with a cast crank and also want to change over to a forged one. Would it be better to go with an aftermarket, something like 440 Source, or find a forged on CL and have a machine shop work it over?
Well I was more going for internally balanced bs external. Also, if I’m going to spend money on balancing and turning then it might as well be a forged crank.Do you need a forged crank? Stock Cast cranks can handle quite a bit.
This is sort of what I was looking for I guess. $400-$500 roughly. I would spend $75 extra to get a forged crank assuming the cost for machine work is the same for cast.Depends on how much you can get a forged one for and machine costs and what you're doing.

Hello Cuda1979 How Much horse power & torque are you trying to get out of your build and what kind of driving will you be doing ? all street ? all track ? if your building a street car with some track use, then your cast crank Will Suet you just fine,Hi my question is can I put a steel crank in a late 70s 440 that came with a cast crank?
Are you still externally balanced or did you (can you even) concert the cast to internal balanced?Hello Cuda1979 How Much horse power & torque are you trying to get out of your build and what kind of driving will you be doing ? all street ? all track ? if your building a street car with some track use, then your cast crank Will Suet you just fine,
I'm pushing well over 600 HP & 600TQ on a Cast Crank with LY Rods, going on 3 years racing this Bad Boy on a Trans Brake Leaving at 3000 RPM shifting at 5000~5200 RPM Running 10.36 @ 129MPH Yup Cast Crank Baby !!! Oh and forgot to mention, including a 250 shot of nitrous with a Progresser.

Yes sir I’m still running externally balanced with SFI balancer and a B&M torque converter, nothing specialAre you still externally balanced or did you (can you even) concert the cast to internal balanced?
You'll have no problem with a cast crank at that level. Leave well enough alone in my opinion.Thanks for all the replies I’m wanting to build a hot street engine with around 500 hp. The reason I’m wanting a steel crank is because I don’t want to put a lot of money in this engine and then have a cast crank break on me. But if some of you guys are running a cast crank with no problems then I might just stick with the cast crank.
