Are you guys running your stock fans on your 235 conversions? I did the water pump adaptor from Pre-'68 Dave, so the stock fan from the '59 engine won't fit unless I re-drill it. Going to Hershey next week, so could look for an older style fan if that would be sufficient. Looking at the Filling Station catalogue, it looks like they are a bit smaller though. I want a stock-looking fan, not something modern if possible.
I also installed the adaptor plate on my ‘59 235 and bought the original style fan for a ‘52. Fits both the water pump hub and clears the radiator nicely.

I went from a 15 " stock fan on my GMC 302 upgrade to a 18 " and shroud. (Standard bolt pattern replacement from Amazon) The performance 302 now never gets hot even when the break in occurred. Cleared stock radiator in my 51 one ton.
