2200 cfm is not going to cut it on a big block. I had a similar problem with my 440 and went down the same road as you, new aluminum rad, new stat, water wetter, new clutch fan, none of it worked. my problem was at idle. even moving at 10-20 mph it would cool right down. I ended up installing a flex fan. I know everyone is down on them, but they cool very well. I used my old electric as an aux "pusher' on the front of the rad.
I'd say your idea about spal fans is a good one. when it comes to fans, either OEM or Spal. If you run a clutch setup, the MP one is way too "long" at least it was on my charger. I bought a short one from bob mazzoliniracing.com. it was expensive, @80 bucks, but I didn't know any better. members here found a parts store one that's way less money. I never got around to installing mine, so I don't know how it worked.

What he negelected to mention is the fact thet he is running a 3000 stall converter and the trans may be slippimg. This is with a 25" tall tire and 3.55 gears. He is running 3000rpm at 50 mph. He's turning some high RPMs at 65-70. I checked his airflow and there is plenty of air getting to the radiator but the fan he's using has a lot of blockage coming out. the fan housing has a bunch of close set ribs, about a 1/4" apart, that seem to keep air from coming out of the fan as well as it should. Timing and carb are good. It will sit forever at an idle or run around at city strret speeds without and heating trouble. I recommended that he cut every other rib off the fan housing and see what difference letting the air out did. I also suggested he swap to a more street friendly converter.

Did you check the timing on the engine, might be probable cause.

Hey boogieart, tell me then how going to a taller tire isn't going to reduce rpm's on the highway? I will await your reply as I await for my 2" taller tires to finish up being installed.
It will but not by very much. you'll see on your way home from the tire shop.
