Last year I ran a bone stock class with a Riviara. Even after though factory gears were a bit too tall, I didn't have much of an overheating problem, but it still got warm. After the fan shroud and additives, I came up with this little idea, I'm sure its been done before, but I thought I'd post it anyway....
I never run the factory trans cooler that's interconected with the radiator, i run an external aluminum cooler mounted to the frame rail. Ford uses a combination catch can (one compartment for coolant overflow and the other for windshield washer fluid). I use the overflow catch can as it should be. The washer tank I will drill a hole in the top, large enough to fit a peice of fuel line through. From the washer pump I will run a piece of fuel line to the radiator trans cooler lower line. Then I will run a hose from the upper radiator cooler line to the hole in the top of the washer fluid bottle. The washer fluid tank I will cram pack with ice cubes, and then fill the remaining space with water, bleed and refill as necessary. We were lucky enough to be able to leave the dashboard in, so for wiring, I conected the ground wire of the washer pump to ground, and the positive wire to the high beam head lights. Once completed, I remove the instrument fuse, so the dash lights don't operate anymore.
When I was strapped in the seat I couldn't reach the headlight switch. Before I strap in, I turn on the regular head light switch. Once racing, and the temp guage decides it should give me an undesirable reading, all I had to do was pull the directional switch to activate power to the high beams (AKA my additinal cooling pump). The ice cold water passes through the radiator via a conductive passage, and picks up heat (leaving your engine coolant SUBSTANTIALY cooler. I could watch my guage drop dramaticly if I activated it under caution.
The blue high beam indicator was also a nice indicator light in case i left the system running.
After the race, we simply left the pump on, removed the (now hot) hose from the top of the resiviour, let the water pump out, and refill with ice / water!

I thought mabey someone could use thius idea. Heck, mabey even a better way of seting it up!

We had a fan and shroud. We built the shroud to cover 3/4 of the blades and all. Even tried a pusher fan. The Riv is such a pain to work with, no room in front of the engine. Well, I'm glad to say next year were building a Caprice and moving up a class.

I'll give you points for some creative engineering, thats for sure.

How did that ol' Riv drive? I've always wondered how one of those FWD V8's would race.

Good luck with the Caprice, I think you'll like the rear drive quite a bit better.

Oh ive run rear drive before. Loved it. Someone showed up with a 89 Taurus SHO and dominated. So I built a 98 Taurus. THAT car handled superb. The 3.0 kept up with the sbc/bbc no problem (I also was lucky enough to use 1st gear on the starts for an extra lauch, then switch to second). For the next season I spliced into the ECM and put a toggle switch in to shift from first to second.
Well eveyone cried FWD!!!
So I built a Riv.
DONT
Chev never made a FWD fullsize - so you can only run buick / olds/ pont..(never had luck with them - just my opinion) The oil pan is deffernt, so good luck finding an inexpensive big block, same with manifolds.
The Taurus drove like it was on rails. The Riv was nothing but push. It was fun trying new things, I like to problem solve - but that thing was a basket case. After 3 motors we built a mid 80s delta 88.

racer17j - stock. Everything is so morphidite in those cars, after several attempts I just went back to stock. Oddball bolt spacing on the water pump, which made spacers unavailable..
I guess I just built it for 1) fun, and to see if i could do it. **** , great learning experience and 2) to give them somthing to whine about. Hey they cried over a V-6 FWD, well I gave em 2 more cylenders worth of crying.
