Let's see... with lots of simplifying assumptions... starting my '69 on a 60-degree day, it takes some 10 minutes of driving to get its coolant to 190F - suggesting an average net heat transfer rate to the coolant of (21.3 quarts / 4 quarts per gallon * 8.345 pounds per gallon * (190F-60F)) BTU / (pound * degree F) * 60min / (10min*hr) = about 35,000 BTU / hour. Is that right? It's been a long day - and that just intuitively seems low...

That suggests that getting 370 gallons from 60F to 110F with the rejected cooling system heat once you've warmed up the main radiator circuit would take... about four and a half hours. Wow, that could sure improve your confidence about making it through a traffic jam without boiling (spilling?) over...

And you'll have to jackhammer the sludge off the inside of the engine periodically...... ;D

Chrisntam,

"I'd say the owner / builder took a $50,000.00 loss."

I think a better choice of words might have been, I'd say the owner / builder took a $50,000.00 BATH.


Have fun,
Steve B.

Now that's funny!

Don't forget to factor in the extra 3000lbs of weight if you are actually able to move.  That would have to make it heat a little faster.   If you were planning a long trip you may want to have some sort of radiator still in there for when the 'interior' got to 110, it would then divert to the radiator.
