Any tricks I can do to the factory carb other than an oem rebuild kit? For the fj60 gotta get back on track here

A correctly tuned oem carb is pretty much the best power upgrade you'll notice.
I have read a little bit about a monster camshaft that may add some torque:

Spark advance tuning and actual ignition timing should also help get optimum economy/power in any setup you go with.\
Holley Sniper EFI did a Hyper Spark distributor that has ignition control which could be adjusted even further.
