Windsors Overheating

[MidOHasp]

Anyone know of any unconventional means to reduce overheating in Windsors (or in general?) Running a 408 stroker, fairly strong (508 flywheel HP, 540 lbft), can't seem to keep it cool. Think I just recently got all the air out as the really bad temp spiking is going away, but when you are into it (and I'm always into it), the temp starts climbing and I have been shutting it down lately pretty quickly. Got too scared watching the temp gauge hit 137C (278F) back when I was spiking.

I eliminated the bulls**t surge tank that I had installed and once the checkbook cools down, I'm going to replace it. Current plans for the next week include:

-Install overdrive water pump pulley
-Remove 50/50 fluid, replace w/ distilled water and water wetter
-Replace stat with Robertshaw unit

I'm hoping from what I've read in some of these pages, that will do the trick, especially once I get a surge tank back on there.

Any other suggestions though? I'm assuming being a brand new SPF, the radiator is good. Just thought some of you in your infinite experiences could offer up some suggestions I may not have thought of.

Thanks!
