I'll be running a temp gauge to see how hot it gets in my engine back...maybe I can compare my results with some of you stock guys.

Running dual 14" fans, fit perfectly. I can see why Lextreme (David) said 15-16" fans would be pushing it and had to chop them up. So far, I did notice an increase in performance, and the engine bay does seem a lot cooler than before. I only did this mod because I did not want to shell out the dough for a fan clutch (mine was wobbling), plus I noticed that the fan clutch and stock fan are HEAVY!!!!
