Intake coolant nipple

[bfarroo]

What are you guys doing with the nipple on the thermostat housing for the heater core. I want to retain the heat in the car so I don't really want to remove and plug it. I thinking about removing the pressed in one and threading it for a 90 degree adapter of some sort. Maybe plug it and drill and tap somewhere else? I'm planning on keeping the ac wether it be with the stock compressor and modified pullies or some other smaller compressor so it's going to be tight in there. Also how far past the last runner do I need to extend the plenum? Can it end right after the runner or will I have to worry about the air being channeled down that runner and causing that cylinder to be lean?

Thanks for any info,

See the ECT, it's spun into a "T", the backside of T
is my 5/8" heater hose nipple.Let's a constant flow
of coolant to go thru head opposite of water pump.

Coolant flowing lengthwise a good thing, neon setup
sucks I think.

So your using that as the actual outlet of the head. That could be a option for just the heater core. I'll have to take a look. Should provide enough heat for spring/fall driving. Would be closer to heater core inlet/outlet also.

With the new car the t-stat will be up front being
RWD, still plan on running a vent hose in same place
to let coolant circulate evenly. No heater core tho

How did you tie it in then? T it in at the coolant line before the rad or tie it back into the waterpump nipple and meter the flow so most of the coolant still goes through the rad? I'm still trying to figgure out some odds and ends.

Head to heater core, heater core to radiator.

Couple options there, some radiators have provision
for a 5/8" nipple. There are also two type's of water
pump, one with nipple another without.

Over the years I like the radiator route, less plumbing
and length's of hose all over engine bay. Both are on
suction side of pump so good flow there.

The green silicone hose in above pic is my feed from
head to core, other hose must be just out of site.

The T was just so I could install ECT in a spot that
saw constant flow of coolant and quick to read temp.

ok so tying in a npt 90* barb adapter on that side of the head should do fine for heater core flow, clean up the engine bay, and also provide more even cooling of the head. Sound's like a good idea to me.
