engine cooler size?

OK here is what I got, a 445 cube Fe 390 with a hot roller cam, no juice and normally asp erated. I am running E85 which inherently runs cooler and synthetic oil which runs cooler still. I will be running 2" primary headers with a good free flowing exhaust and a 19/30 afco two core radiator. Also one of Jay's 55 gph CSR pump setups. With all that considered how big of an engine oil cooler should I run with a thermostat installed? Thanks guys .....Jon

How big is the oil pan and capacity?
How much extended long distance driving?
I've run a stock pan and 7 quarts for years at long distance highway and never really felt the need for
a oiler cooler. I do put a piece of cardboard in front of the rad on cool days because I have to much cooling. lol
On the big engine I will need an oil heater. 
You don't want the oil too cool or it will not cook off the moisture and cause snot to build up in the valve area.

Got an 8 quart Moroso pan and want to add a 180 stat to the cooler. I am building it for road race and highway use also, when I attend races, cruises and shows it will be driven there. It does get up to 100 degrees here and traffic stops to a crawl frequently toward Chicago.
