The cam manufacturer recommends the 15w-50 or equivalent.
With oil temps at 360F I'd be using that 10w-60 redline you acquired and I'd be looking for more.
Even a straight 60 grade if the truck is a warm weather only vehicle.
Amsoil makes a v-twin oil in the straight 60 grade.
Because of the insane oil temps you are experiencing I'd look to a motorcycle specific oil. They are made for the extreme heat that can easily creep up on a big cube air cooled v-twin when moving slow or stuck in traffic.
Then I'd add a friction modifier like mos2 just to help because v-twin oils have lots of zddp but no moly,and I dropped 40f using mos2 in my Harley based on using my temp gun pointed at the heads.
With oil temps that high you need a fan cooled oil cooler and a serious oil.
Try that redline you suggested right off the bat. Get a few used oil analysis done to establish trends then thicken or thin based on the collected data.
I'd stick with a redline product and if they've got limited options then I'd go with a v-twin oil from amsoil.
Those are insane oil temps. You need something that is overkill,redline products are formulated with overkill already inside.
And being poe/pao is a definite requirement and redline has it.
I have a friend who runs a straight 70 in his promod. I think he said it was Kendall synthetic.....but hes running a blown2500 hp alky drinking hemi.
