Thank you all for your input. It gives me several things to consider. I would like to use a 7 blade fan and clutch, but it appears that would neccitate a 2 core radiator for clearance. . I would like to use a 3 core copper, but then would probably have to use a different fan set up. Maybe I should use a 2 core aluminum since they are available looking like stock. Paul, what sealer are you using on that exhaust manifold stud? Mopar sells a sealer that has Mopar label on it and is black in color. It dries to a rubber like consistancy rather than silicone. I really like it and will probably never use silicone again............................MO On Nov 29, 12:36 am, "Paul L. http://1962to1965mopar.ornocar.org/ml-lennemann63.html" <pjl...@xxxxxxxxx> wrote: > Steve, my 63 as you know has a similar 440, stock 2 core radiator, no > shroud, auto tranny running through the rad + an extra cooler.
