[LS short box]

I like and use Spal fans on my LS swaps.
On my 68 C10 I used a Afco radiator and a single 16" Spal fan. Biggest radiator I could fit. It's a generic LS dual pass. You also get them as a SBC dual pass.
No shroud.
I've had it in 95 degree heat in heavy traffic and no over heating. ECM controls the on at 205 and off at 195.
