Hi everyone,
I have a dalumma, Swap or Rebuild my 2000 5.4l motor out of my 2000 Harley truck. I am planning to spent some money am remove the motor and rebuild the rotating assemblies. I'm looking for 400-450hp
I am finding out that there is'nt much for upgrades for this motor. On the swap idea not sure what would fit with little fab or bolt on a procharger.
My tranny has been rebuilt with a monster maga kit, rearend 4.10, jba shorties headers, superchip which i dont like at all. I'm also running 100 shot NOS and my superchip will not let me change the timing.

Can someone point me in the right direction

thanks
