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.
