As the title suggests what radiator are you using? Putting a 5.3 with electric fan or fans in a 87 V10.
Thanks!

Check out Tejas Steelworks. I've got their engine mounts, transmission mount and fan shroud made for dual 13" Spal fans on my truck. I'm using the Spectra CU730 factory replacement big block radiator in my '85. Also have the factory big block radiator cushings/bushings and the upper mount from LMC.

Works fantastic and keeps my truck cool even in the dead of summer in the deep south. Getting close to 50k miles on this setup without a glitch
