Diff gear recommendations

Thanks for all chiming in guys, and I apologize for lack of info on my part. I'll include more.
I emailed Cass/Dr Diff, for the 741 the gears are Korean made. Everything else with "kit" is USA.
I emailed Motive and theirs is Korea as well?? Website says Italy tho??
The trans I have is original 67/904.
The cam is an old school Comp 20-247-4
I bought here(probably too big but couldn't pass up)

I'm thinking like OMM said it needs more stall obviously, but do that first?
Thanks all.

Steve Motive performance gears in the Orange Box are made in Italy , they also have Blue Box street gears for some makes (9inch Ford etc. ) also made in Italy ,,, they do have gears made somewhere in Asia and are cheap price wise ,, the part number for these gear sets has an A at the end . i do not think they make the cheap gear for 8-3/4 differential. even Timken bearings has gone offshore i am seeing more made in China on their boxes and other boxes say the bearing is made with imported components. if you need a complete differential let me know , you may have seen my diffs at Moparfest.
