I came across a 4.380 stroke Callies forged crank and was wondering how much block clearancing I would need to do (440)? I have been thinking about doing a Stroker build for a while but wasn't going to go that long on the stroke.
Can I still use the original oil pick up or will I need a special setup? Would that crank need special pistons or rods?
This is going to go in a 72 cuda that currently has a 440 in it running a best of 11.673 but is mostly street driven. Would the 4.380 crank be too much/overkill?

Myself I would pass on it if you are looking to just build a nice stroker for your street car. Thats gonna be a bit of work trying to make it work in a stock block if you plan to use a stock block. I went with w 4.15 crank in my stroker as it cleared good in the 440 block I used and was only close at my oil pick up. I use a .030 over 440 with the 4.15 crank for 493 cubes. I wanted to keep mine very simple and easy so it did not run into alot of money. Just my oinion but it sounds like that would be alot more work going with that much stroke. Ron

The crank has been sitting in the guys garage for a while and has some light surface rust on the journals. He said if they were turned down to .010 it would be a good piece.
Even for cheap it sounds like I should pass on it. I was originally wanting to do something like your engine Ron but when the oportunity came up to get this crank for a couple hundred bucks I thought it might be worth a shot. I really don't want to fool with external oiling in my street car. The block would be a stock 440 block. Bore is currently stock but next time around will most likely end up 030 over.

How much HP do you want to make and more importantly why has a crank that expensive been sitting in this guys garage rusting for a couple years? What did it come out of ?
I wouldn't even consider buying it without a magnaflux test. Since it needs to be turned .010 you might consider cutting it down to 2.2 rod size as that opens up your rod selection immensely. But yes that is custom piston territory unless you get lucky and there is a shelf piston/rod combo that would work with that.

I didn't end up picking up the crank today but did get a 440 short block so let the games begin  it's a '76 vintage with stock pistons, crank and rods. I am thinking about either a 4.15 or 4.25 stroker crank. I am not sure what hp I want but I would like to build a solid street/strip stroked 440 that doesn't require a lot of maintenance. Right now I have a standard stroke 030 over 440 with trw six pak pistons (not zero decked), 84cc eddy heads, 509 cam, eddy rpm intake, mighty demon 850, in my 72 cuda. It has been in the car for 10 years and am just looking for more. I have the following parts that I will move over from my existing engine and/or are already in the car - 84cc eddy heads - eddy rpm dual plane or mopar m1 single plane - 850 mighty demon - comp cams pro mag rockers - msd 6al - msd billet distributor - hooker 2" primary headers into 3" full exhaust - 727 w/reverse man valve body and 10" turbo action vert - 4.10 gears - 28" tire - pump gas Based on the parts above would you go with a 4.15 or 4.25 stroke crank? Any cam recommendations?

I was kinda leaning towards the 4.25. Would it be bad if I didn't port the eddy heads? I was just hoping to build a good bottom end and then bolt on the heads/intake/carb from my existing setup to save some $. I figured that alone would be far better than what I have now.
Any other cam recommendations?

I dont know what to tell you on the cam, Im thinking 265* @.050 .600 lift for something mild or 270*@ .050 .625 lift for more race then street. Id use the Comp SQ designs.

I love my 440 source 4.500 stroke crank. Hi fives in the 1/8 and still getting faster. 
I see that 440 source does have the 4.5 stroke crank for a RB block, thats news to me.
Can it be used with with the stock internal oil pickup as the OP desires. If so that would be a viable option for the OP, IMO
But ,Im going to guess not.

My stock 440 block stroker uses a 4.375 crank with chevy rod journals, .030 over gives 520 CID. Muscle Motors (steel rod) stroker kit (they built the short block). I had MCH port the "stealth" heads, used a stock Hemi pan, stock 1/2" pickup, it all fit fine, used the MP stroker windage tray out of the box with no mods. With stock steel valve covers (I did have to do interior mods to the valve covers for fit) and blue paint, it looks like a pup. In your cuda high 10's should be possible if you can get the torque to the ground! The heads are a little small for that displacement (it's definitely NOT a "race effort" type engine), but it sure does pull down low and is a great street/strip engine! Spend as much as you want on valvetrain, I went with 1.6 rockers and a .590 MP solid, a Street Dominator intake and 950 HP, and 2" headers. Runs 122 in the quarter in my 70 RR, your car should be lighter.

If I remember the story right the crank was out of an alcky car and the guy said after a season of the rods smacking on the crank journals they develop cracks. Said if I had It manga fluxed it would show cracks but if it was turned down it would be fine for a pump gas car. That scared me a bit so I didn't pull,the trigger on it. IDK...does hat story sound right? How much would I have tied up in machining the used crank vs buying a new one?

That old crank can be a real can of worms with a lot of work to bring it into usable shape. But if it is center counter weighted, that is worth a VERY good look. Those center counter weights take a lot of stress out of the combo, and help a stock block live a lot. So for my $$ I would see if the current owner will go along with the plan of having it magged, to make sure it will clean up when stroked. Then tally all the expense of making it useable, and see where it compares to an off the shelf crank.
I would put the biggest stroke in it that will work with what ever oiling system you are willing to run. Check into all of your options on external oiling systems before saying no to the idea. In a street car, big cubes are the best for all around driveability and low rpm torque. You can run a very tight converter and still ET very well. A 4.5+ stroke motor makes a real impression on you when you hit the loud pedal. And with rpm heads and a 4.5+ stroke, you can shift it below 6,000 rpm and run like a scalded cat! Look at the 4.5 stroke kit from 440source for piston and rod options. I believe they have a long rod, dished piston combo for streetable compression.
