I mean... if you look at what CarlC has into his set up and what it does performance wise... the $695 he spent on the radiator... would tell me to sell the current radiator and step up to what it is that you really need vice that of slapping a bandaid on your current cooling system.

Option #2...

Hang a stack cooler on the front of the core support and deal with it. It's the only other choice that will actually provide enough of a cooling benifit for the cost involved.

Anything that you place under the car, under the trunk etc etc... will need dedicated, directed air and an external fan for it to even worth it's consideration. But, that increases it's complexity ten fold....

Does he have a website? Does the $695 include the elec fans? Been happy with my AFCO unit but I need cooler oil on the track.. that's a proven fact.

The minimum line size for an enginer oil cooler in any application is -10 (1/2")... and allow me to stress this... the very minimum size. Ideally, -12 is perfectly suited for the majority of applications here... but there are some that may even require -16 for the feed with multiple -12 returns.

The associated in tank auto trans cooler is much too small fitting-wise and capacity as well.

Although... it may be used for the return side of the power steering... in lighter duty applications.

Thanks for clearing that up!

I had planned on installing the cooler under the floor plan due to the limited room in front of the radiator because of my intercooler. The trans cooler is already being used for the trans. My biggest concern would be a presssure loss. Im using the lingenfelter adapter and the line sizes are -10 at the oil filter area.

Mine is more like the NASCAR type. I got lucky when I purchased it. The radiator was on closeout and scored it for $400 or so. It's really too big for the car. If it was 3" narrower it would be perfect. And no, it does not come with any sort of fan for $625+. The good stuff is going to cost more up front, but in the long run will be less expensive than having to do it all over again.

The hottest the oil has ever been was 240*, and that was with a 106* ambient, 130*+ on the track, 20 minute session with the old iron 406.

I don't see why your tank could not be modified to accept a cooler. The question is, as Tom points out, is how much will it cost? If it could be done for less than 1/2 the cost of a new radiator, then OK. If more than that you might as well sell the one you have and buy the Big Kahuna.

I don't think you will be happy with an undercar cooler. Too many compromises and likely an ineffective system. Think of how PO'd you will be if you found out it was not effective and you had to go the in-tank heat exchanger later on? $$$$$$$$ and time (that's free.)

Maybe I could still run my current single fan with thier shroud? That would save me $ plus I wouldn't have to mess with the electronics. They would also have to be able to put the in and out both on the pass side (LS Setup).

damn.. this site is always costing me cash.. lol

The C&R does not have a shroud. It's a blank on both sides.

Mine is dual-pass with fittings on the passenger side. However, they are sized for Gen1. You would want them fitted for LS sizes. You could also have the in/outlets modified for angle/height/length/curves to accomodate a standard hose.

Measure your fan width and height before making the call. That way it will be easier to narrow down the choices. Max total width for the lower tanks would be helpful as well.

Something else to think about. If I could do it all over again I would make a lower mount/upper plate similar to a 2nd gen. Basically a floating mount so that the radiator is not hard-mounted to the radiator support.

Not surprising. A similar build to the previous 406SBC in another f-body car had the same thing happen. He had to back off for several laps to get the oil temperature down even with a Canton road-race pan. Water temperatures were not abnormal. High RPM will make oil temperatures rise much faster.

Welcome to the Tom and David spending plan.

Like Carl said.. not abmormal.. 205ish I think.
