I'm not one of the seasoned pros here. More of a researcher for what to do with my truck...
As far as I understand the engines all bolt up. You will probably want to swap the accessories from the truck engine and the intake for the torque and ease.
Should make more power and weigh around 80 lbs less. I would use a truck friendlier cam.
I've been all over on what to use in mine but pretty set on Trick Flow 220 heads and a Brian Tooley stage 3 truck cam. I don't think you'd go wrong with either.
Alright guys, if I told him wrong, chime in.
