I have a 1954 235 installed in a 1934 chevy master with a modified 6 3/4" harmonic balancer that accepts a serpentine crank pulley in front that drives a MP90 supercharger. The short high water pump places the fan in the correct position and allows the use of the 54' fan which is "flat backed" and clears the serpentine idler. I have about 15 miles on the installation now, cools fine, runs good.
I need someone to point me in the right direction for a pulley to slow down the water pump/fan. It appears that 6 1/8" pulley is max diameter before I hit the water outlet on the head and this would be a great improvement over the 4 1/4" current pulley which is turning almost 1.6 times the crank.
I have a N.O.S fan blade but I remember puting a couple of blades through Dad's hood about 50 years ago.
Do I have any options or should I just have one made.
All fits under the original hood!
Thanks for your assistance, Jerry
