I plugged them with gasket maker, a plug, and hose clamp:




There are four total. One is behind the engine which I still need to plug. And one off the expansion tank.

How robust is the heater core in these cars? Up here in the NW it rains a lot and defrost with heat can be a necessity in the rain.

I would say I may have removed 10 lbs total. That is the heater core itself, the lines, the hoses, the water valve, and all the fluid. Where I am (PA) we get a decent amount of rain. I was going to try anti-fog wipes (Rain-X) to prevent the windows from fogging up.

What's the point? You get no heat and defrost. For 10lbs?

I am looking for ounces and inches (aren't we all). I am building my car for a different series. I don't need heat and possibly won't need defrost.

I updated a post above. It seems as though you do need the line that runs from the bottom of the expansion into the side of the block. Live and learn.
