Looking for opinions here. Since I put the big block in my /forums/images/graemlins/k5.gif my fan is roughly 5-6" (closer to 6) from the radiator. The radiator is a 3 core but I'm getting a new 4 core this week. I already have a 2" spacer but I still need to get a fan shroud too. With the current setup it runs about 195 with a 190 thermostat..might get up to 200 just sitting. I know the 4 core will put it about an inch closer to the fan and I'm pretty sure the fan shroud will help a lot too..if I can find one. Thought?? What's your spacing from the rad?
