Help... my car is overheating

Okay, I've ran out of options. I read your message on overheating and can't seem to pin point the problem. Things I've done so far:

1) Brand new radiator.
2) Removed the thermostat
3) New fan clutch
4) Added K&H Bloc Seal - Hoping it would help if I had a BHG.
5) New radiator cap

I did remove the fan shroud because it was damaged but I doubt if it would overheat because of that. I've ran it for an hour and a half in the drive way. Take it for a ten minute trip on the freeway doing speeds up to 90 with no problem. Head back up the hill which is about a mile and half with about a 40 degree incline and it OVERHEATS. The temp gauge goes immediately to red and the radiator begins to bubble. No bubbling in the reservoir.

I read that I could a have air lock and should burp the system. I've set it on an incline ran it for an hour with the heater on so I'm assuming that's enough though I'm still getting small bubbles when I take of the radiator cap. Also, what is the viscous fan. Just a weekend mechanic who loves his supra (87 non turbo) so please make your answers for a "mechanic dummy". Thanks for a great forum.
