What type/brand antifreeze should I run in my BB 396/325 with AC? Seems to be way too many choices now. Everything is close to stock. Also what mixture ratio? I live in VA and rarely does the temp get below 0.

Zerex GO-5 or equivalent, 50-50 mix (it won't leach lead out of soldered radiator and heater core solder joints like the Dexcool chemistry will); the good old "green stuff" (Prestone, etc.) will also work just fine. Both will raise the coolant boiling point to 265*F with a 15# cap and 50-50 mix.

Thanks Jonhz! That is basically what some of other post say. I'm hoping to crank the big iron this weekend.

what about aluminum radiators will the dex cool hurt those in anyway, I thought the dex cool was made for aluminum radiators?

Dexcool is fine for aluminum radiators - most all modern cars have both aluminum radiators AND aluminum heater cores, and that's what the Dexcool chemistry was developed for; it's not so good for our older cars with soldered copper/brass radiators and heater cores, as it leaches lead out of the solder joints over time, which weakens those joints.

You can also buy the pre-diluted stuff also.

And do not use tap water need to use distilled water.
