| Tom,
Just google "laminova oil cooler" and you'll get lots of info. Warning, they're pricey and a bit on the heavy side, but work very well. Beware of using flimsy oil coolers. We've had a few oil cooler failures on the list.
960 cu in sounds like a good place to start. Ed Anderson posted a cooling calculation spreadsheet a while back. I'll look to see if I can find it, or maybe Ed will read this and post it again.

Hi Mark: Almost called you today...but got distracted. So would 960 sq in cool the oil with a dedicated plenum. Also where might I have a look at a Laminova cooler?

The oil cooler on my P-Port 20B is approx. 10 x 11 x 3.5 (going from memory), but I'm also running a Laminova oil-to-water exchanger in series. The hottest oil is sent to the Laminova, then to the oil/air exchanger. Return "cool" water is routed through the Laminova on its way back to the engine. If you're looking to cool 400 hp using only oil/air coolers, I would double the core size of my single cooler. Of course, this all depends on the effectiveness of your intake and exit plenums.
