I did this once on an '81 Jeep CJ7 4cyl. Power loss was substantial
at higher speed/RPMs and it sounded like a jet engine about 2000 RPMs.
You really need to have a fan clutch on the smaller engines. On my
78 Chevy it was not much of an issue. I ended up removing the fan
entirely and got an electric that mounted to the radiator. I believe
I got it from JC Whitney for about $60. Worked great. my .02
