That expensive dual fan setup is now on a shelf waiting for me to try it again in one of these old trucks. It may never happen, but I got it if I need it,lol.
The 454 in my '71 runs real cool with a stock clutch fan setup and 3 core radiator.

I had the same problem in both my tow truck and my pickup. I never had any luck with the electric fan set-ups. Went back to the correct shroud and a fan clutch. Never had an overheating problem since
