Looks like our 440 was built for a 4speed. Wondering if there’s a way to change this to make a 727 fit or if I would need to swap out the entire crankshaft? Let me know. Thanks
440 with 8 bolt crank 4speed to 727 ? How do I do it

I mean where the 727 mounts onto the crankshaft. The hole looks like it’s for a 4speed is there anyway to change that or does it come that way? I have the correct flexplate right now. I’m just wondering if there’s a way to make it fit or if I’d have to replace the crank shaft? Or just remove something there on the engine side of the crankshaft?

Remove all that stuff that is in the center of the crankshaft, and the torque converter snout will fit in there.

I can't see what's going on in your picture, the resolution is too low. You may need to pull out a pilot bearing to make room for the torque converter snout.
I posted on your other thread. Just take the pilot bearing out of the crank. What is all the gray stuff smeared around the bolt heads? I hope thats not ARP thread lube. If it is take it apart and clean it all off. I use Loctite.
Pictures are a little tough to see, but it looks like a "Dakota" roller bearing was pressed into the hub. This was a common fix for cranks that were not finished for a standard .940 pilot bushing. Pull the whole assembly out, and the converter hub will fit.

All correct above. Hemi 8-bolt flex plate and remove the 4-speed pilot bearing

I’ll ask my dad what kind he put. And what’s wrong with aro if he used it?

How do I remove that? Asking for my dad
If it is ARP moly lube you can wash it off with brake clean or carb clean. You will have to rinse them and blow dry the bolts and the crank holes several times until perfectly clean. Blue loctite on the bolt threads and torque to specs.

Use a puller or pack it full of grease and find a snug fitting driver and force it out hydraulically.

Ok so I marked them in the picture as 1 and 2. my dad says he can remove 1. But how does he remove #2. The outter ring one. Same way you just mentioned? Or is that officially part of the crank?
Also sorry to bug you. And we really appreciate your help! We aren’t experts when it comes to engines. This one is supposedly rebuilt and good condition
Check with your auto parts stores. Lots of them will loan the tools out.
Harbor freight show them. https://www.harborfreight.com/search?q=pilot bearing puller

My dad likely has the tools but does that 2nd outer ring (the more yellowish one) also come out together with it? Or do I need to do something else to get that one out?
Not sure. But it does have to come out.

For the 727 torque converter to fit. It does. Won’t fit without that one coming out
