A bit of an update. The truck got a new power plant, and before that went on I put on new headers, and ignition. I still have the stock air intake with an aftermarket filter. It's getting new high-flow cats, and the PCM is from BlackBear customs. I'm pretty happy with how it runs and drives. It's got a lot more get-up than before, especially with the PCM.
I'm still running a 10 bolt with 3.73s. I picked up a 14 bolt SF with 4.10s but i'm debating on if I want to go through the trouble of changing gears; I don't really tow anymore and it seems to run fine with the 315s.
How much good would it do to swap out the clutch fan for a dual electric setup? I found a deal on a set of fans from an 05 chevy truck, but is it actually worth it to swap the fan setup?
