Time to winterize the hot rod. What is correct to use in a B engine with stock radiator, aluminum water pump & housing, & aluminum Eddy heads?

You can use any type with aluminum, just have to change it more frequently. If you are going to change it every winter, as you say, you have nothing to worry about. Mix 50/50 with DISTILLED water. That is a nice looking car

Since 1971 there have been any number of imports with aluminum heads and using "regular" antifreeze with no problems. Datsuns, Toyotas, and more have had no corrosion problems. So it isn't necessary to use a special antifreeze unless the manuffacturer wanted to go fancy, and those experiments haven't been that successful.

I'd go to Wal-Mart and buy Prestone's "all engines" stuff, it's from a reputable company and you can find it everywhere. Job done.

The new style global works well with any car.thats pretty much all we use at work and I use it with my aluminum headed 440.Just dont use DexCool.Rocky

is that madness as in top fuel hydro

No fulie hydro in my past. I ran a '63 aluminum max wedge dodge superstocker in the late 60's & early 70's out of Amarillo, Texas. It was called "MADNESS" & our '69 Hurst AMX superstocker was called "MADNESS II"
