For Delcotron 10 or 12si alternaters
Battery terminal on alternater (big post) to power source (This must be connected to the main power switch(not the ignition switch) so it kills the power when the switch is turned off, otherwise the engine may still run when the main is turned off. Use #10...
So far , here's my combo: shroud that fits tight against the rad covering 1/2 the fan with 3/4" clearance around the fan, Afco rad, 3/4" restrictor, 25% underdrive pulleys, 6 blade steel fan, short stock steel water pump.
I might try the 4 blade fan.
Thanks for all the info.
Thanks for the replies. How close do you run the fan to the rad, or how long of a spacer? If you underdrive the pulleys do you need the restrictor? Do you run mechanical advance in the distributor or is it locked out and if so is the motor hard to start?
Need tips on keeping a sportsman cool:
what size fan
how shroud fits
water pump
pulleys
rad size
rad cap #
size restrictor
timing
jetting
Any suggestions?
