newest question - heater not working and engine overheating

i'll take a look tonight to see if the manaual outlines all the hose routing for the 76 318. right now i cant rive more than 5 mins without the temp gage sailing up to the high level. first time there was smoke at the upper rad hose where it meets the rad. second time no smoke but temp gaga still way high.

also now the heater isnt working. i have the 2 big heater hoses hooked up but i dont recall if i hooked up any other sort of hoses. and i did plug a vaccuum port on the back of the manifod - should that be going somewhere ( i think it was going to brake booster but i am not running that)?

doh - always something1
