I am looking at the 16" puller for my I-6 wih no A/C. I originally got the 2360 cfm, however it won't clear the waterpump as it is 3.39" deep. The 1300 cfm which is only 2.05" deep will fit. Does this seem like it will do a sufficient job cooling? Is anyone using one like this on their 6 cyl's? As usual thank you for your ideas and input.
