    I have been an advocate of the GM cores for years. I had difficulty
cooling a  
    Mazda powered GTPJr car with a large conventional radiator. I added a GM
core
    in the stock water heater connections and the problem was solved. After
that I
    used one for oil cooling on many cars of my own and made them up for
others.
    Just one of the very few things that works too well and is too cheap to
pass up.
