You want to buy Dexacool which is red/orange, not the regular green antifreeze. Havoline makes some for a reasonable price that you can get at any parts store. It's like $30 a gallon from GM and Havoline is like $10-15 a gallon.

there is "new" stuff out by prestone that claims to be compatable with ALL fluids and ALL colored fluids red or green... I used this stuff on a 160 T-stat install . so far so good ... and coincidentally it's green ... maybe this stuff is the exception to the rule

OK, sorry to hijack, but now I have a question. Do you need antifreeze at all?
I ask, because I live in New Orelans. We NEVER get below 30*, and my car is kept in a garage. Also, it is pretty much a race only car - driven on the road 2-3 times per month. Doesn't regular water have better heat dissipating properties than antifreeze?

Not for "anti-freezing" purposes, but you should still use antifreeze for the rust inhibitors and lubricative properties it has. It's better for the cooling system to not run pure water.

I just saw the new Prestone green, and it is good for all systems, red/orange or green and can be mixed, I personally wouldn't do it though. They also have a GM approved Dexcool type coolant (orange) that will also be fine to use..

Since our engine blocks are aluminum and not iron, the cooling system is exposed to much less gunk, therefore, the recommendation that the antifreeze is now good for 100K.

Just goes to show you that you can't trust everything someone says, even a company. Probably pretty easy to get away with, being that it is coolant and not to many people check it or drain it often.
