I'm looking at your notes, and I'm going to look at the boat later this week. Right now I don't see any reason why this wouldn't work. As a matter of fact, I may consider doing this with some big ball valves so I can switch back and forth (that seems possible at the momemt, maybe I will wake up from the dream later.
I've had bad results with the heat exchangers, and virtually everyone I talk to who has them on the big block Chris of this era has the same comments "they're good for a boat anchor" or something like that.
I'll give you my comments after I've had a chance to look at the system in person.
cheers,
