I will try to add a picture, the left hole is the aligning dowel and the middle hole and the right hole should line up.

I think the register hole in the crank & the TC nub were enlarged in ~68 or so & you can use the later crank/early trans (like you are doing) but not the other way around & the gap may or not be OK as is but I think people have done it & there was an article in a van magazine where in addition they cut some slits in the flexplate so it would flex & not wear out the pump bushing (iirc, not sure, I have it somewhere). Doug Dutra of the old /6 club of America used to machine a spacer to take up that space & later wildcat auto was selling em (not sure if it is needed & or the /6 one is the same as the V8 one) but it must be desireable otherwise it would not have been fabbed by several individuals. I have one if you need dimentions.

All 727 converter pilot hubs are the same 1.81" diameter. The Poly motor trans case has one hole that won't match the LA engine, drill/tap.
The '63 727 input shaft spline is different than the '67 and later, must use '62-'66 converter or change input shaft.

I didn't read the intermediate posts between OP and here, so beware!
The bellhousing has one hole that doesn't line up, the lowest one on the driver's side. Many leave the bolt out. Because this bolt is the lowest , below the centerline of transmission and crank, it is important to have some clamping force at that point. I found that I was able to drill a new hole and tap it but I could have also used a bolt and nut. It doesn't have to be a huge bolt. It could be one size smaller than the others and still do its job.

I was not talking to you. If your comprehension equaled your arrogance you'd be the genius you think you are.
