Maddog13407 Posted October 2, 2011 Share Posted October 2, 2011 Putting a 300+ and 10 speed roadranger into a single axle R600. got new mounts made up and engine mounted. the fan on this engine has a clutch and is 24'' with about 8 blades where as the old 711 had a 23'' regular fan on it with 5 blades. my question is is it ok to mount the old fan up as the bigger one with clutch wont fit into the shroud. Will the smaller fan cool this engine enough? thanks, Matt Quote Link to comment Share on other sites More sharing options...
theakerstwo Posted October 2, 2011 Share Posted October 2, 2011 A freind of mine at work has a four valve 300 set hot in a 66 r model.It has a air/air cooler on the front and i will look at it some more.I know the air/air is against the grille.

Maddog13407 Posted October 2, 2011 Author Share Posted October 2, 2011 This engine has the air cooler on top of the motor, the plenum that says Mack across it, doesnt have the air to air in front of the radiator. i want to use the original radiator and shroud. just wondering if the old 711 fan will keep the 300+ cool enough. the 711 had a spacer behind the fan so it stuck out a ways also but the clutch/fan is too big to fit into the shroud. the engine is an ETAYZ673 out of a 1980 Rs600L. thanks, Matt Quote Link to comment Share on other sites More sharing options...
