Yes Kevin, technically correct. I should have expounded on my use of 'heat exchangers' when talking about engine cooling specifically.

The following pictures are what I would consider my 'normal' application in cooling... this is actually what I talked CarlC into doing (I'm really good at spending his hard earned money.) I typically like to package both engine cooling and oil cooling for the numerous and mutual benefits. I have used this set up to cool and control the cooling of 850-1000HP use in places like the desert southwest (Phoenix Az and Las Vegas Nv, etc.)

This utilizes a 13 plate heat exchanger for engine oil cooling... however, it works almost too good... and I would recommend the use of a oil thermostat as to not over cool the engine oil.

I tried the heat exchanger setup on my big block(666hp) and it wasn't up to snuff with a stock width radiator core and the most extreme conditions. (Road racing sessions) I've since separated the oil and water cooling by going to an air oil cooler. It's made a big difference in temps but I haven't been back on the track. I think a heat exchanger could possibly work with the additional width of the autorad set up and larger fans. Big blocks make BIG heat. :unibrow: I went with the heat exchanger to help get the oil up to temp faster. It worked but ultimately overworked the cooling system. If you don't plan to take the car to extremes, you don't need as much cooling.

I figured you were talking about oil cooling. I feel that I can always add an external system down the road if it is necessary.
When you talk about extreme conditions, are you meaning just cruising down the road in Az or Las vegas, or auto crossing/racing in that heat?

That was my thought too, thinking that two separate systems would be best. That being said I am sure an integrated system would be fine in my application (not being a big block). Also a good point on the wider system vs stock width system possibly making the difference as well.

I thought you were talking about an old school LS7.

^^ No sorry. It is a gen IV LS7 with darton sleeves.^^
hope you didn't lose interest all of a sudden:_paranoid

Auto-X, open road racing and land speed racing... which makes street cruising down the strip with the AC on... on a 114* day look like child's play.

Not trying to heist a tread, But what is pricing on these setups.

Thanks Kirk

I have been discussing with Paul at C&R in Mooresville, NC about BBC radiator, electric fan setup, etc. They are in the development process now and plan to have a prototype for me to try out in March. If interested give Paul a call. I know they have the LS and SBC stuff completed.

Paul used to work for Be Cool and DSE, so he is aware of our needs/wants when it comes to pro-touring, Auto X, road racing ,etc.

Kirk it is not my place to give prices that I have gathered over the last little while but you are starting anywhere from $900 to over $2000 depending on options..
You should probably contact some of the vendors on here if you want solid prices..

I have a PRC rad waiting to be installed and I just placed a order for an condenser and overflow tank. They are good guys to deal with!
