5 blade cooling fan options
Does anyone have any accurate dimensions on the factory 5 blade fans that were used on 69 and 70 big block Novas. I have a factory setup and I only have 1 5/8" between front of water pump snout to a factory 4 core radiator. Just want to make sure before I spend the money on one. Any help or recommendations on would be appreciated.

Re: 5 blade cooling fan options
I believe the fan is about 17.5 in diameter...can confirm, but that is pretty close. As for clearance between the w/p and radiator...the factory 5 blade has a 'relatively flat' profile, so you should be fine. Keep in mind there were no 'factory 4 core radiators' on the BB Nova [69-70]...only a 3 core. But, a 4 core will work, I have done it several times.
You will need the correct BB shroud and the engine has to have the correct stands/mounts for the everything to line up properly. wilma |

All my brackets and mounts are correct the only thing that I am not sure about is that it is a new gm crate 454, standard long pump. Would you be able to confirm the distance out from the water pump. This is the car it is going on.

If you use the correct Nova only fan without a spacer it will work.
I can take a picture if you like. |
