68 c-10 327 stock cooling hookup

[fivemilepoint]

I am a novice with a 1968 C-10 LWB (no A/C) with a 327 that came with a 2bbl Rochester carb that is being replaced with a rebuilt Rochester 4bbl carb and matching intake manifold. Right now the cooling system has a 110V heater which needs to go (no winter driving any more) and the old hookup had a plumbing tee on the intake manifold for the temperature sending unit that also needs to be corrected.

My question is that I would like to update up the cooling system correctly and was hoping that someone has a stock 327 and can point out the correct fittings/hookup for the cooling system, particularly at the intake manifold.

Thanks for your help.
