It's been over a month, get a cherry picker and pull the block from the stand and measure the darn hole already. That's the only correct way to do it.
Like i already said, the engine is on a stand and will be staying there for now...

Undrilled I believe, I was actually watching this thread for the bearing info (no need to double post). I have mocked it up in the floor, dealing with flywheel issues, so I haven't installed everything yet. Currently need a trans cross member I think, I haven't sorted through all my STUFF yet. 
yea but which bearing/bushing did you end up with?

If you'll notice I joined this conversation late last night and since then I slept and went to work. I am in Pa and I live & the car is in Fl, so as of yet I haven't installed a bearing or bushing. I have purchased a number that haven't work so that is why I think I have an undrilled crank (OD of the bushings have been too big, ID fine on the input shaft). As mentioned I came to this thread looking for an answer, which has been provided by an earlier post by someone. The way I see it, I need to pick up a bushing for an undrilled crank available from NAPA OR a roller bearing OR the oversize bushing that goes in the convertor flange. If I pick up all 3 then surely I will have something on hand that will work. The extras can just go in with the rest of my stuff. If I were you I would do the same, they cant be that much money and at least you will know that you have what you need. My schedule may be ahead of your so if I determine which one works the best for me, I will post it, possibly as soon as this week end. 
Careful, your character's showing!

Thats understandable, no worries man
The only reason I keep asking is because as most of you know parts stores need application specific when ordering parts. I cant just go in and say I need the oversized bushing or undersized bearing. Without part numbers or a specific application they are lost, and therefore so am i lol
Im thinking that with the depth that I measured today that my crank may be a drilled crank, but I could be wrong since im not sure what the depth of the drilled cranks are

Mine has the depth, it's the width that I believe is referred to as drilled or undrilled. Maybe someone with more 360 experience can clarify for both of us.

are you serious man? LOL this whole time i thought drilled vs. undrilled meant the depth hence the having to chop off some of the input shaft if using the torque converter hub bearing
now im really confused

I thought is just from deductive reasoning, not based on anything I have heard or been told. As I mentioned, I am looking for an answer as well. The clues/facts as I understand them, 1)if a crank is undrilled it requires a different pilot bushing, 2)the difference in the bushings are the OD 3)there is a third bushing option that uses the convertor flange area instead of the "normal" bushing area. All these point to (for me anyway) that all the shafts have the depth (I haven't personally seen one that didn't and I've looked at a bunch but not EVERY engine) but not the bushing width, ie not drilled for the bushing. I have heard that the reason some shafts are cut is for use behind a GM due to its strength over a muncie, fact or fiction this is what I understand. I do not know of a case where it was necessary to cut the shaft to put it behind a Mopar engine and I have bolted a fair amount of stuff together from varying applications.  Again, I would yeild to someone with more real experience with different facts and 360 experience to correct me. I only learn not get mad when corrected.

Here is the roller bearing I used for a 73 - 360 block. This one fit w/no mods needed to seat the bearing. There was plenty depth drilled for the shaft too. Again, it was a 73 - 360 block.

Do you know what vehicle that would cross reference from? If I give the parts guy a national bearing number he will be lost since all they know is make and model stuff.
Also, in terms of talking about drilled cranks, is it in reference to the depth, diameter, or both? maybe you can clarify this for us
I was going to go ahead and order the mopar torque converter hub #53009180...I am concerned though that if my crank is drilled, and this bearing being for undrilled cranks, that it may be too small in O.D. to fit in my crank. Then I am not sure what I will need

Get the number from the picture or even print the picture and have then cross reference it. Go to start thinking simpler!

Trust me, thats how I think already, its the parts guys dont know anything! lol..all they know is vehicle specific. I will try, but id like to know the dimensions of this bearing and what it is similar to...is it similar to the torque converter hub bearing? or is it for drilled cranks?

It is the convertor flange style bearing, you should be able to see the area on your crank. Post what you find and if I beat you to it I will do the same.

Maybe it's time for a new parts guy.
Amen to that. I was looking for a pinion seal and the kid behind the counter sounded as if he knew what he was talking about. He sold me the wrong part by looking up the specific application. Said only two were available. You guessed it he was way off. The seal he sold me was for the 489 case, my car is a 68 and the 489 wasn't available untill 69 as I hear it. Totally wrong application (?) back to the same chain different store. The guy was 56 years old and knew mopars as well as all vintage cars. Told him I had a 68 with the 742 carrier and he got me the correct part the next day. It was right in the computer (?) Same Chain different fella. Makes a difference. If your guys can only look up make and model, go find a new parts supplier. That simple. You are indeed over thinking this. Good Luck.
