I'm planning on changing the cooling fan for the summer.  What sizes are other people using, the T-bird vendors seem to be selling 16 inch, but it seems that there is enough clearance for a larger fan and I want all the cooling I can get.

Thanks,
Don

I think Vic's comment about removing the pump spacer is the right way to go - and if I re-engineer my set-up again (too many versions already) - I'm going to either remove the spacer or get a modified pump with the wider impeller.

Pretty sure the factory fan on my '57 Bird is 18".
