IMO a few things i see in the OK video. First is converter converter converter...Your converter is not helping anything for sure I woudl go looser for sure there. Also I would work on "freeing" up the cars front end as well. Would also work getting the larger carb to work better, not a bug fan of the Holley"1000", I would consider a different option there(4500). IMO with what you have there I think it could benefit from more.
