Sorry it's radiators again

I'll tell you what works for me;
Group 1
A 26"A/C rad from a 73 Dart, installed into a widened core-support hole. Yes it is from an automatic car.And I used the shroud that came on it..
I also used the big 7-blade all steel clutch fan from that car, and all the pulleys.
I installed a Milodon hi-flo water pump and matching stat. This pump has an anti-cavitation plate on the bakside of the impeller
I used molded hoses only, and the lower one has the SS anti-collapse spring in it
I went down to the FORD dealer and purchased a thermostatic clutch for an early 2000s pick-up truck
I run the rubber seal between the core support and the bottom of the hood.
-----------------------------------------------
Group 2
I installed a 7 qt oilpan on the engine and run it at 5qts
I run fresh cold air into the carb.
I restricted the coolant bypass hose to something like 40%, but I use the heater as a bypass on cold mornings.
In the early years I ran straight water with the anti-rust and bearing lube additive. But eventually switched to 50/50
I removed the front license plate holder.

This system cools my 420 hp 367 cuber without hick-ups of any kind, and since I had most of the junk laying around, it was pretty cheap. We are talking occasional strip( been twice, total maybe 5 runs) but the rest,100,000 plus miles. is all street. Hi-speed,low speed, parades, stomp after stomp after stomp, traffic, towing,whatever, the gauge never moves.All these parts are still on the car, most from day one in 99. The Ford clutch went on in about 2004. The Milodon pump maybe 2002. Actually, now that I think of it, that pump made a big difference.I'll guess it's the plate, and they are available separately for cheap.My engine runs at about 205*F as measured with an IR gun.The stat is labeled 195*

I'm pretty sure many of these things might not be absolutely necessary.I just know that in the big picture, Zero heat problems is hard to mess with.So I'm not about to change anything.
I think the stuff in group 2, might be optional. You could eliminate the Ford clutch, and run a 7-blade fan directly. I think that clutch cost me about a $100. If you run a direct fan, you might get away with a big 6-blader from the junk pile. But forget about any flex-fans. The one I tried was hopeless.With the anti-cav plate,and direct drive fan, you might also be able to get away without the rubber core seal.The Milodon pump was about double a stock 8 blader.
