The prevailing setup on the Pantera which is very similar in overall shape and size (low to the ground, little front air intake area, long coolant tubes, etc.) is two sucker fans with a slightly laid forward radiator in order to provide room to mount the fans. Most use a fully shrouded radiator enclosure in this case. I personally am still running and original brass radiator with two fans mounted on the front blowing and in this case no shroud and have no issues. It would be interesting to see the flow data from the SPALs of the world which is more efficient, a fan blowing or a fan sucking from the back. And yet I see no shrouds on an SPF, ERA or the original GT.
