I was planning to put one of these

and hook up the stock fan. It would still use the heater tubes in the longs like a stock system. By locating it in the engine bay, routing should be less of a hassle.

Couldnt a guy make some Heat exchangers for the V8 exhaust? (IMG:style_emoticons/default/confused24.gif)

Maybe with marine exhaust manifolds, but it's water heat. If you had good sheetmetal skills, a hot air exchanger could be made.

Yes!Hot air xchngr is what im talking about.Not that hard.Has anyone done this?

I like that box, where do you get it from?

They've got some great stuff! Is there any reason why this couldn't be set up as an external oil cooler? I'm thinking that if you run one on each side and connect them up to the tube in the longs you could have heat like crazy regardless of whether you are aircooled or watercooled.

Ernie, that's basically what I had in mind, except I was going to start with one and go from there.

The Renegade Hybrids under dash unit has the capability to run the air hoses up to the defrost vents or vent it out directly from the unit into the cab.

I have a 71 Chalon with a SBC. When building the car, I incorporated a heater core in the fresh air blower case and ran a couple of feet of heater hose from it with the intention of someday getting it all connected. Well, that day is here. My question is whether it's feasible to tie the the heater core lines to the radiator inlet and outlet hoses via T's instead of running the heater core lines back to the engine's intake manifold and water pump.

What do you think... doable?

Surely someone has an answer; an opinion... something! (IMG:style_emoticons/default/biggrin.gif)

Sorry, I didn't see the question. Yes, in theory you should be able to flow a heater core from the inlet and outlet of the radiator. Flow will vary based on things like hose size, port resistance, parasitic drag, pressure differential, etc... But it should work. If you can find a Y fitting and point it the right direction (with flow) it should work better.

Like this...

Thanks. I think I'll give it a try and see how it goes. What's the worst that can happen... no heat? Already there!

This might be a silly question but if I design the system so the heater core coolant T's off the radiator inlet and radiator outlet hoses; how does the coolant know to enter the heater core from the radiator inlet T and exit into the radiator outlet T. Or do I have that reversed? Or do I "T" in and out of the radiator's inlet hose? This is confusing!

Pressure differential. it will flow. This is where angle, T size and internal resistance come into play.
