Do i have the right clutch fan

duster510 said

the mopar clutch is too long, thats why i went with the hayden/jag clutch......and the heat and hills.....heat is around 80-90s cali summer days and the hills are maybe 6%-9% grade from 2-10 miles long....i will try and watch the temp gauge and shut it down if she gets hotter than 220-225...if i coast down hills she chills rite down within 5 miles...

Im ready to rip out the pice of crap 318 and go 360 or a 408!!

I run the same fan clutch, it's a good piece. Here's the theory with the higher temp thermostate (180 versus 160) I recommended in my first reply. The 180 holds the coolant in the radiator longer, so it can cool the water before it enters back into the engine. With the 8 blade water pump and the 160 thermostate your moving the water through the radiator to fast. I had this very same issue in a 340 Dart I built. Changing thermostate is cheap and easy item to try as a fix. You may also need to go to a six blade pump, but I would try the thermostate first.
