Sorry it been some time since the swap.
I have 7000 miles on the new motor and have had no problems. I ran the stock injectors and Throttle body from the Ram with no problems and it pulls hard.
The hard part was making the relocation brackets for the AC and Altonator
I used the truck timing cover and ground the top down to make some room for the intake. But I also had to make spacers to lift the intake 1in.
I used pacesetter shorty headers and ground the ports to mach the 6.1 heads.
I had to make a y pipe and move the cat 14in back.
If I had to do it again I would not use them. Lots of work to make them fit.
In the spring I'm going to try some 6.1 jeep headers and make a new y pipe.
I also used all of the stock sensors for the truck and the belt is from a 98 v8 with the ac delate .
I have not had it on the Dyno but did race a 2011 mustang 5.0 and got him by 3 car lengths
with the stock tune.
On important note is to make sure the 6.1 you have has no clutch bearing in the back of the crank !!! It took me 2 day to figure out why the engine would not mate to the Trans!!
