I have a 1968 road runner, original 383 4spd, i put a 26'' howe aluminium radiator and want to put a good electric pusher fan. what do you guys recomend i use? i would like to use a dual fan.?? any help would be apreciated.

There are a few good posts on electric fans, but all of them are people using them instead of the stock fan, so they are using them as pullers, not pushers.

I tried pushers before, and there just isn't a lot of room in front of the rad for this.
Biggest I could get in front were two 10 inch fans, and they didn't move much air. In fact I think they hindered more than they helped.

Dual fans do not make good use of the radiator area on our cars. Dual is good for low and wide stuff like alot of late model cars. A big single is way to go here.

Get an automatic controler and set it up to come on way above your thermostat temperature and off just above your thermostat temperature.

Upgrade the alternator, wiring and use relays.

Any particular reason you want an electric fan instead of a tried and true clutched mechanical?

SPAL the best fan. CK the amps when deciding

Never go with a pusher. They don't work unless you've got the time and money to engineer something.

Fans from a parts house suck. No further investigation necessary.
if you're going electric, plan on a 50 amp startup draw and 30 amp running draw. If you're not going to run somethign taht heavy and have the charging system to support it, stick with mechanical.


Some of us enjoy the benefits of an electric fan such as on demand cooling with the engine off and no whirring finger chopping instrument of death under the hood.

You ain't gonna like this suggestion but I know they work, the Powermaster 140 Amp alternator 8-57529 from Summit for like 250.00. I had one on my car, running a BG400 pump (with a step down box) Two Spal PUSHER FANS (with a custom shroud) a MSD Digital 6 box and a CSR waterpump. The lights never went dim at stop lights and the batteries stayed charged and the engine ran cool (for a Mopar) once I got my Jetting and Timing correct. I also used a 8 gauge cable to feed the batteries in the trunk, had relay on the headlights, fans and fuel pump and fantastic 1 or 2 gauge ground wires. Here is the alternator in Black...

I realize upgrading the alternator and the entire electrical system would be best, but it is really necessary?

If getting rid of my pulley driven fan also requires spending a couple hundred on another alternator, then forget it. The few extra HP saved isn't worth the expense on my car.

is this a street car that will not stay cool or is it a race car?

If it is a street car I have seen really good cooling achieved with a solid mounted fan, I have used a Flex-a-Lite STEEL blade fan and when positioned about an inch from the aluminum radiator and inside of a proper fan shroud it kept a 383 based 477 engine (3,800 stall with 4.56's and 28" tires)in a 66 B-body under 195 degrees while in traffic, this was Hemi Dave's STREET car and it ran high 10's low 11's IIRC he would drive it to High Speed Welding every morning from Chicago. This thing did idle about 750-800 rpm and did NOT have a fan clutch (solid mounted to water pump)so this fan does work. I would NOT use a Flex fan or Aluminium bladed fan-but that is just me...

Fan Description: FLEX-A-LITE 1617P 17.25 " dia. Inexpensive fans which provide maximum airflow at low and high rpm.
These Flex-a-lite race fans are the industry's highest rpm rated fans. Their all-metal construction makes them rigid and ready for abuse. They're available in your choice of all-steel or steel and aluminum blade construction with a tough black finish. under 30 dollars mail order, but you will need to get a spacer...

Street/strip usage. I don't have a fan shroud on my fan right now, and I know that is the real problem, but I'd rather not screw with trying to make or modify another shroud to fit my radiator and fan when I can get a used OEM fan from a junk yard for $10-20. And it would take care of the cooling problem at the track too.

Guess I'm greedy. I'm looking for the cheap and lazy solution

I know a few friends that have had luck with Ford T-Bird/Mark VII and Mini Van fan shrouds, so when you are out grabbing your fan take your radiator measurements and see if you can't pick one of those up on your next trip! I love yard scrounging, it's better than a trip to McDonald's

Chevy HHR fan+shroud is the perfect size for a 26" radiator with a 22" core:
