Thanks a lot guys. Getting encouragement like this makes me want to work twice as hard. Especialy since you are the ones that built and are building the cars that inspired me.

I'm sure after my engine gets in I'll have a very long weekend.

I have a few ideas I'd like to toss around for getting my coolant from the front to the back. Ahem...

1. Run round tubing inside the main tunnel. Send and return. Pro- Neat/cleaner look, practical since everything else is in the tunnel Con- Tight space, and I havn't figure out a good way around the rear torsion.
2. Run one pipe inside the tunnel and one on the passenger side. (right next the tunnel) Pro- Not as clean, but clean. Con- A big hump on the passenger side of the tunnel, and the rear torsion.
3. Square OR round tubing under the car. Pro- More room than the tunnel. Con- Might limit ground clearance, and I'm a little uneasy about the pipes under the car.
4. Heater channels. Pro- Clean! I can check for rust while I've got them open. Con- A lot more work.

I'm thinking either 1-1/2 or 1-3/4 diameter. The radiator inlet and outlet are 1-3/4. The engine I don't have yet. I can always get an adaptor to a smaller diameter for the rad or weld a smaller diameter pipe on it. (I love TIG ) As for material, Aluminum, Stainless, and Carbon Steel are all options. But the cost might be a limiting factor. I have the capibility of welding all. I kinda want to say away from copper. Question... Would a smaller diameter pipe put a strain on the water pump by restricting the volume of water it can move? I'm an aircooled guy.

I'm sure I missed a few pros and a cons, But I've just gone blank on some of them. And please excuse all spelling errors.

Let me know guys. I'd sure love to have another perspective on this.
