spring mod
Lust is correct doing this mod helped my cooling tremendously. I probably got a little overzealous with adjustment though. temps were stable at 185-190 and ran that way for 7 years. Also did other upgrades along the way 8" crank pulley, 6.5" waterpump pulley, WP clearance to minimum gap, all filler panels, air dam and AC plates helped as well. The new CC radiator also is no slouch and just wanted to see what result would be or if I needed to go back to a 2797. All I can say is the 2797 served me well and that is what I would use with slight spring mod. Good Luck Gerry
