Is this fan too small?

[Madgyver]

I'm going to try electric...
It's a 14" Derale 1350 CFM, 1750 RPM, 10.5 amp draw.

not near enough CFM in my opinion. don't even attempt it below like 2800.

why not just leave the fan on i gave you?

Ben,
Trying it out for now since I had intended to have the electric one on before the trip. If it doesn't keep it cool the mech fan will go back in. If it does the mech fan will live in the copper77 with the 351C.
Thanks again,
Honorio

%) %) %) I would think you should have at least a 17" fan good luck. Bill %) ;D

The Black Magic with almost 2 1/2 times that CFM was not big enough to keep my 408C happy, Mad....it was back to mechanical for me. Curiously, I have plenty of room between the fan and my raddy...even with the big 460 Camper Special fan blade and a 351m/400 fan clutch.

Fan Size

Hi Mad!!!
Re your fan Nope not going to cut it.
It has nothing to do with size of fan it is the amount of air it moves.
If you want push configuration, you have to build in a substantial increase in flow. I use two 10 inch fans pushing have no problems
If you are in pull mode (tractor) you can use a single 14 inch.
A few tips for you
getting air in is not the problem, getting the hot stuff out of the engine bay is.
Ensure you have a good venting system for exhausting the hot air out and your fan problems decrease dramatically
I made a vent on the top of the hood and this really helped. Ended all the cooling problems

Electric no fit so its back with the good ole mech fan and radiator protecter.

Cooling problems at idle...

Hey Mad, I was wondering what the final verdict was on your cooling/fan situation? I ask because I too have a 351C that I just had rebuilt. Took it out this weekend and when I was stuck in traffic at idle, the temp started to creep up, quickly to about 230 and would have kept on going. Found an open space and headed for it and the temp came back down to about 170. Mind you I have a mustang hood scoop for outflow of air. Any ideas or advice or comments about your trial and error enlightenments?
Thanks!

I think a lot of the older Ford 302s and 351s had a thermal vacuum switch in the goose neck with a line that went to the back side of the vacuum advance on the distributer. It retarded the timing when the idle temp got high to increase the rpms for more air flow. Just a thought.

Um.... don't use the plastic zip ties...

Oh the shame, I couldn't resist.

Stone me now please.
