Sounds like you still have air in the system....burp, burp, burp the air out. Air will cause it to overheat quickly.

Things to check.

1, as MORSNO , Sdeeter said, air in system

2, Old Dexcool scale clogging the block and radiator ( pressure flush block and radiator)

3, a 160 thermostat ( jegs or summit has 'em)

4, Do NOT take offense to this.. Make CERTAIN your serpentine belt is on correctly. Some set ups allow you to install it wrong, pump runs backwards, and engine starts and overheats...

Good luck@!
