Hot Rod magazines engine masters video show a loss of 30Hp on a I think 350hp Chevy 350 with a mechanical fan. So maybe 10%?

My off topic Phaeton was noticeably quicker off the line with out a fan using a '32 water pump and adapter. While cruising at 25mph the water temp was at 180. Stopped it overheated pretty quick of course. This was a Race of Gentlemen car and I had a 9in electric fan that I hung in front of the radiator in the pits to cool it off.

So is 4hp worth it on a stock Model A? In my opinion nope. I would just put on a Snyders hi compression head as Paul said.
