We're running 2 12" Spal brushless fans in a Derale Shroud in front of a LS swap Cold Case radiator in my son's 79 TA. It works perfectly, the engine stays at the temp we set in the Terminator X software regardless of the temps outside, A/C in use, etc. We could have also set up the fans using their proprietary temp sensor/switch, but there's more controllability through the EFI software. The Spal brushless fans sit inside the shroud somewhat, so if you're interested in going in that direction, you'd need to make sure FMG fans are thick enough. Also, we experimented with 14" brushed fans in a modified cold case shroud, but there was interference with the steering box. We could have made some other changes to make it work but it didn't keep the car as cool as we wanted so we bagged it. I suspect his shrouds take the width needed into account, but may want to double check.

Mike originally designed his shrouds around SPAL units and addresses that directly.
