So what kind of replacement camshaft do you go with?

OEM or aftermarket are probably equally reliable. It's the labour involved for replacement that makes it non cost effective for the most part.

I have done several camshaft jobs on 6.4Ls now, a couple of them using the stage 2 from Colt Cams. Geoff there tells me the stock cam has a 0.005 jump right where the lifter begins to load, this causes the lifter to fail, which in turn takes out the cam. I have not accumulated sufficient mileage to prove that the Colt camshaft is fail proof though.

1) there are third part CAM providers that provide CAMs with reduced base circles , this reduces excessive drive train tension.

2) there has been a problem with rebuilt short blocks and "reman engines" in that the heads are planed to straighten them out.....but nothing is done to account for the shorter drive train distance. if you plane your heads you need shorter pushrods

3) while 5W40 is acceptable year round....if you are running a stock truck with DPF in tact,, the best option is to run 5W40 during the coldest part of the year and a higher weight such as 10W40 or even 15W40 during non winter times of the year. this helps prevent CAM damage caused by highly diluted oil . 10W40 and 15W40 has a longer way to go before loosing lube value than 5W40 as the oil gets thinned out with fuel.

I ran 15-40wt only in my 6.4 and changed it at 5K intervals.

I did many blackstone OA's. My fuel dilution was non existant for the most part. No idleing and no in town stop and go driving was the rule. That doesn't mean I didn't but that was not the primary use,

Yes, Plugged in. Our temps here near DC in the winter average around 30F in the winter.

I have a commuter car for the cold days.
