G'Day Doc,There's also an option from Ron Davis Radiators. You can get it for an auto or manual transmission, and there's the option of adding dual spal fans. Like it was mentioned earlier in the thread, if you want to run cooler, you'll need a cooler thermostat. You should get the Motor Rad thermostat from Amazon and the URD thermostat spacer (I have the URD 160 degree thermostat, but it only maintains 190's). You'll have to modify the thermostat housing to accommodate as well. But you can get operating temperatures in the 170's, although keep in mind that aftermarket thermostats are rated for what temperature they START to open. Not the actual operating temperature. If you need additional cooling capacity, the RD radiator is the premium option......Not cheap though, I'll warn you in advance.
That is a sweet set up ...very sexy...well done.
A few years back I spoke to Dirty Deeds about an dual E fan set up, but on their advise didn't pursue it.
But I did end up doing a simple setup - putting a push fan in front of the Rad, that I manually control / cabin switch. Only need it when slow crawling to force more air thru.
No where near as uber cool or effective as a dual E fan set up like yours, still it works, coupled with hood louvers, helps move air past the engine.
