I have flushed the radiator but I really believe the installation the previous owner did is the problem. The engine has high compression pistons (pings on mid grade gas, ok on 93 octane), the fan in front of the rad is blocking air and the C4 tranny is generation quite a bit of heat. With the cooler behind the rad, it just complicates the problem. The other question I don't know is how accurate my temp gage is (VDO). I'll have something to contribute when I get this fixed.

52 panel, flushing the radiator alone doesn't help much. You have to take it to a radiator shop and they remove the top tank and run a brush down the rows in the radiator removing all the junk inside. You'd be surprised how much crude come out and improves the cooling. I'd definitely check the gauges for accuracy before spending a chunk of money. Looks like you have some issues to deal with.

push or pull ??
Nathan,
you didn't say pusher or puller, but I'm assuming since you mentioned shroud it's a pulller. That (from what the experts tell me) is the best way. Mount your a/c condenser in front and pull the air thru both. at highway speed you don't need any fan and the speed will push the air through the entire core.. in some cases a shroud could actually hurt you.
I just ordered a PRC aluminum job http://www.streetrodstuff.com/Products/159/ downflow.. 1 inch dual tubes 2-3/8" core 14 fins per square inch ..Air director fin covers with a/c condenser in front and a 16" Spall pull fan in rear...I don't plan on a shroud and Dick all but guaranteed me I'd never have any cooling problems...
Are you driving the truck yet ??? I think before I spent a pile or reengineered the wheel I'd see what it does in traffic in your roasting 70° summers in those high latitudes.. I can't imagine if you have good flow thru the core that you 'd have a problem with the 16" pulling thru the core...
you mentioned the 'easy' way of mounting ??? haven't we taught you better than taking the 'easy' way... come on boy... spend some time fabbing up some really cool... hard to make... expensive one off brackets... you embarrass me son... taking the easy route
I sure hope 'fenders doesn't hear this... he'll be soooo disappointed in ya...
later
