Mark....... your right, what would you say would be long term usage?

I have had the exact same block in my system for almost 2 years now. And its a copper aluminum block. With total success.


and I ran an all aluminum spir@l (Firstone ever made) for a very long time. With simalure results. Hell all that happened to that block was the channels got a little discolored. More from the blue food coloring I put in the coolant then anything else.

the fact is that yes, copper and aluminum excelerate corrosion. But with the right measures taken................. it works. Now does it work just as good as an all copper block...... YES it does. Are the possabilities of corrosion higher then an all copper block. Cant dispute that at all. Its been tested, proven, and is a fact. But if its done right, and like most perfectionists here........ well enough said.
