6.1 Swap Won't Rev Past 3K HELLLLPPPPP!!!

After talking with the guy at hotwire, sorry I am bad with names lol we figured out something interesting. After closer inspection, one of the troubles codes stood out. The oil pressure code. Well, it seems that the 05 hemi trucks had an oil sending unit for the gauge, as well as one for the ecm.

Seems a little odd to me that without an oil pressure signal to the ecm it would even start. I guess running under 3600 rpm with no oil pressure is okay in a Hemi!! I wonder if that will cure your extended crank time as well?
Good luck and keep us posted.
