Late 5.0L block numbers?

Just rang Norm at Aussie Desert Coolers, I think this coupled with the fans will beat my cooling blues.

the current rad I have would cool a Hot 6 pretty easily, but unfort not a mild 8.

ohh also, there isnt any different between fans that pull the air or push the air, its just a matter of undoing the nut in the middle of the blade and turning it the other way round  ;) ;)

It's even easier if you just reverse the polarity.  :o

Hi.
Yes, I realise there isn't any difference in the Push or Pull type fans ::). My point was, the fans mounted in front of the radiator are usually a thinner profile, so it would beat his space restrictions. No use getting big arsed fans, if they don't fit ;)

I didn't know that fans had arses  ???  So that's where that weird smell is coming from  ;D

.. Just an update on the cooling situation.

HQ cut down core, with ttrans cooler front mounted.

I made an alloy shroud to suit the 2 x 12" fans similar to Boris' one (the rumbler).

the engine fan (flexalite black) was removed and the fan and shroud set up to SUCK.  the performance of the fans sucked, IMO the engine fan alone was far superior.  there was a marginal improvement in stationary cooling ability, however cooling at over 60kmh was severely compromised with engine starting to overheat at speed.. this was a step in the WRONG direction. "Water Wetter" was used as well.

obviously the shroud and fans limited the ability of air to pass thru the core.  my guess was it created too much air pressure behind the core.  in addition the density of a 4 row core was too much for the twin 12 " fans.

what to do?  replaced engine fan and put fans in front of radiator to PUSH.

mounted trans cooler forward of the fans.

The push of air coupled with the pull of air behind the core generated by the engine fan works superbly.

at idle in traffic it does not go above 190F and most of the time sits around 180F (82 C).

on the freeway it sat around 180F the entire time.

Conclusion,
thermo fans when used as primary cooling fans is inefficient, or requires a shroud which does not restrict air flow at speed.

thermo fans are best used as supplementary fans to the main engine fan.

engine coolant temps decreased, but unsure if it was as a
 result of cooling fans,
cooling fans and water wetter
or water wetter only.

I am not going to experiment by removing the water wetter.. it costs 25$ a bottle!

A shroud fitted to the engine fan side of the core will also improve efficiency.. perhaps this was all it ever needed anyway.

An article on setting up a burnout car in SM done by one of the "legends" said he fitted a truck/tractor engine fan to his chebby to get more air through the radiator.

that would work, but could you imagine the noise!!

we put a BIG fan on the EH which has a warm 179, you can hear the fan noise long before you can hear the motor.

it keeps its cool but sounds like a windmill on a gusty day.
