Rebeldryver's '65 Impala SS Black Betty

Don't particularly like the offset pictured but these have potential - as do the summit brand 5 spoke, and they have conical seats.

Nope. I'm just how to have fun with this setup. I'll let the bozo's and douchebags worry about internet numbers glory.

And isn't that what it's all about having fun!!!!.... I'm sure no matter what your going to be grinning from ear to ear the first time you stab the throttle!!!........ Hey and congrats on getting it ready to go!!....... I have always loved your car!!......

If you are not having fun with your hobby, then whats the point of doing it?

Realistically, my initial setup and tune will maybe get 500 hp at the wheels, up from the current 325. Should be fun.

The first step for the turbos starts today. Making more room under hood and improve cooling.

This has been a long time coming Scott...you must be itching to get into it.

Got busy yesterday after going to the swap meet on the electric fan change over. The fan shroud was made for my friend Carl's 67 Chevelle. He said he had a 65 Impala three core radiator in it. After his car was wrecked he went crazy with a $1000 radiator, shroud, fan setup on his car. This car has only ever gotten hot sitting in traffic. As long as air went through the radiator, it kept cool.

This is what I started with: A noisy flex fan behind the radiator with a chromed fan shroud I got from PAW years ago. Remember PAW? It got some dents when two fans blades on my last fan came off when merging onto the freeway. How they didn't mangle the radiator or cut the hoses is anybody's guess.


The car did get warm if I got caught in slow traffic for extended periods of time. Also, when sitting in staging lanes on hot days. So, I put this 16" pusher fan on the front. It worked. I originally ran it off a thermostat controller until one day I was stuck in traffic on a blazing day and when I went back to driving 70 mph; it never shut off and the engine stayed hot. I had to pull it's fuse to shut it off. The big pusher fan would block air from going through the radiator at freeway speeds. So, I added a shut off switch and a light so I knew when it was running.



The Hayden thermostat finally quit last year so I just wired the switch wire to the in line fuse. I just hit the switch when I wanted it on. It's not ideal because the fan will pull power through the smaller switch wire instead of the big wire drawing right off the battery with a relay and thermostat.


After I pulled off everything.



This is the fan shroud I mentioned earlier. It survived Carl's wreck, but the fans did not. I got a pair of 12"ers and attached them with button head screws.



The shroud fit pretty good using existing bolt holes in the radiator. I had to egg a couple holes, but no big deal.


Now, I needed to wire it up. I got a cheapy non-adjustable thermostatic switch from Autozone. It did come with a wiring harness and relay.


The thermostatic switch is a probe type. You thread it through the fins of the radiator. No problem. The fins are mangled anyways from the previous fan shroud and pusher fan.


After I got it all wired up.



Since my temp gauge quit a few weeks back, I used a temp probe thermometer. The damn switch never switched on going up to 190*. CRAP!!


I finished the day by bypassing the thermostatic switch. Flipping on the fans the temp probe dropped 30* almost instantly. I will have to figure out the temp switch.

That should work pretty good compared to your old set up. Free up some power too. I'm not a "fan" of fixed flex fans.

Hey Scott, each fan needs its own relay and run a thermostat switch that runs in the head or intake..but you probably know this.

The wiring harness was setup to run two fans, I had to add my own inline fuse for the second one. The heads don't have temp gauge provisions (really annoying) and the intake's is getting used by the temp gauge. Maybe I should get a thermostat housing with a port for one. This is not the best setup, wiring wise.

Interesting....I would have done it differently....a clutch fan and shroud should fix it up just fine.

What temp is the switch supposed to switch on at? could be it never got that hot at the place you mounted it? Can you attach it to the upper hose somehow?
